  10. Working from the Command-line

1) Installation Instructions


A binary executable of the latest version of the gen3-client should be downloaded from Github. Choose the file that matches your operating system (Windows, Linux, or Mac OS).

No installation is necessary. Simply download the correct version for your operating system and unzip the archive. The program is then executed from the command-line by running the command gen3-client <options>. For more detailed instructions, see the section below for your operating system.

Note: Do not try to run the program by double-clicking on it. Instead, execute the program from within the shell / terminal / command prompt. The program does not provide a graphical user interface (GUI) at this time; so, commands are sent by typing them into the terminal.

Mac OS X / Linux Installation Instructions

  1. Download the latest Mac OS X or Linux version of the gen3-client here.
  2. Unzip the archive.
  3. Add the unzipped executable to a directory, for example: ~/.gen3/gen3-client.exe.
  4. Open a terminal window.
  5. Add the directory containing the executable to your Path environment variable by entering this command in the terminal: echo 'export PATH=$PATH:~/.gen3' >> ~/.bash_profile.
  6. Run source ~/.bash_profile or restart your terminal.
  7. Now you can execute the program by opening a terminal window and entering the command gen3-client.

Note: If your Mac OS X does not allow access, you need to manually allow it under System Preferences > Security & Privacy > General (click the lock icon to unlock, enter administrator name and password).

Windows Installation Instructions

  1. Download the Windows version of the gen3-client here.
  2. Unzip the archive.
  3. Add the unzipped executable to a directory, for example: C:\Program Files\gen3-client\gen3-client.exe.
  4. Open the Start Menu and type “edit environment variables”.
  5. Open the option “Edit the system environment variables”.
  6. In the “System Properties” window that opens up, on the “Advanced” tab, click on the “Environment Variables” button.
  7. In the box labeled “System Variables”, find the “Path” variable and click “Edit”.
  8. In the window that pops up, click “New”.
  9. Type in the full directory path of the executable file (for example, C:\Program Files\gen3-client).
  10. Click “Ok” on all the open windows and restart the command prompt if it is already open by entering cmd into the start menu and hitting enter.

Note To download the latest version of the file from the command-line, use the following commands from your terminal:

# Mac OS:
curl https://api.github.com/repos/uc-cdis/cdis-data-client/releases/latest | grep browser_download_url.*osx |  cut -d '"' -f 4 | wget -qi -

# Linux:
curl https://api.github.com/repos/uc-cdis/cdis-data-client/releases/latest | grep browser_download_url.*linux |  cut -d '"' -f 4 | wget -qi -

View the Help Menu

To check that your copy of the client is working and confirm the version, the tool can be run on the command-line in your terminal or command prompt by entering gen3-client. Typing this alone or gen3-client help will display the help menu. For help on a particular command, enter: gen3-client <command> help. Note that you must provide the full path of the tool in order for the commands to run, for example, ./gen3-client while working from the directory containing the client. Alternatively, you can add the location of the gen3-client executable to your shell’s PATH environment variable.

2) Configure a Profile with Credentials


Before using the gen3-client to upload or download data, the gen3-client needs to be configured with API credentials downloaded from the user’s data commons Profile (via Windmill data portal):

  1. To download the “credentials.json” from the data commons, the user should start from that common’s Windmill data portal, followed by clicking on “Profile” in the top navigation bar and then creating an API key. In the popup window which informs user an API key has been successfully created, click the “Download json” button to save a local copy of the API key.

    Get credentials.json

  2. From the command-line, run the gen3-client configure command with the --cred, --apiendpoint, and --profile flags (see examples below).

Example Usage:

gen3-client configure --profile=<profile_name> --cred=<credentials.json> --apiendpoint=<api_endpoint_url>

Mac/Linux:
gen3-client configure --profile=demo --cred=~/Downloads/demo-credentials.json --apiendpoint=https://nci-crdc-demo.datacommons.io/

Windows:
gen3-client configure --profile=demo --cred=C:\Users\demo\Downloads\demo-credentials.json --apiendpoint=https://nci-crdc-demo.datacommons.io/

NOTE: For these user guides, https://gen3.datacommons.io is an example URL and can be replaced with the URL of other data commons powered by Gen3.

When successfully executed, this will create a configuration file, which contains all the API keys and URLs associated with each commons profile configured, located in the user folder:

Mac/Linux: /Users/demo/.gen3/config
Windows: C:\Users\demo\.gen3\config

NOTE: These keys must be treated like important passwords; never share the contents of the credentials.json or gen3-client config file!

You should receive an error if you enter an incorrect API endpoint for your credentials. For example:

~> gen3-client configure --profile=demo --cred=~/Downloads/demo-credentials.json --apiendpoint=https://nci-crdc-dem.o.data.commons.io
2019/11/19 11:58:12 Error occurred when validating profile config: The provided apiendpoint 'https://nci-crdc-dem.o.data.commons.io' is possibly not a valid Gen3 data commons.

You should also receive an error if you provided credentials that are not related to that API endpoint. For example:

~> gen3-client configure --profile=demo --cred=~/Downloads/wrong-credentials.json --apiendpoint=https://nci-crdc-demo.datacommons.io
2019/11/19 11:58:15 Error occurred when validating profile config: Invalid credentials for apiendpoint 'https://nci-crdc-demo.datacommons.io': check if your credentials are expired or incorrect.

To confirm you successfully configured a profile with the correct authorization privileges, you can run the gen3-client auth command, which should list your access privileges for each project in the commons you have access to. For example:

~> gen3-client auth --profile=demo

2019/11/19 11:59:04
You have access to the following project(s) at https://nci-crdc-demo.datacommons.io:
2019/11/19 11:59:04 CPTAC [read read-storage]
2019/11/19 11:59:04 DCF [create delete read read-storage update upload write-storage]

3) Upload Data Files


gen3-client upload


For the typical data contributor, the gen3-client upload command should be used to upload data files to a Gen3 Data Commons. The commands upload-single and upload-multiple are used only in special cases, for example, when a file or collection of files are uploaded to specific GUIDs after generating structured data records for the files. These two commands are described in further detail in sections 7 and 8 below.

When data files are uploaded to a Gen3 data common’s object storage, they are assigned a unique, 128-bit ID called a ‘GUID’, which stands for “globally unique identifier”. GUIDs are generated by the system software, not provided by users, and they are stored in the property object_id of a data_file’s structured data.

When using the gen3-client upload command, a random, unique GUID will be generated and assigned to each data file that has been submitted, and an entry in the indexd database will be created for that file, which associates the storage location of the file with the file’s object_id (“did” in the indexd record, see below for more details).

Options and User Input Flags

The following flags can be used with the gen3-client upload command:

Flag name Required? Default value Explanation Sample usage
profile Yes N/A The profile name that user wishes to use from the config file. --profile=demo
upload-path Yes N/A The directory or file in which contains file(s) to be uploaded. --upload-path=../data_folder/
batch No false If set to `true`, gen3-client will upload multiple files simultaneously. The maximum number of file can be uploaded at a same time is specified by the `numparallel` option --batch=true
numparallel No 3 Number of uploads to run in parallel. Must be used in together with the `batch` option. --numparallel=5
include-subdirname No false Include subdirectory names in file name. --include-subdirname=true
force-multipart No false Force to use multipart upload if possible. --force-multipart=true

Example of a single file upload:

~> gen3-client upload --profile=demo --upload-path=test.txt
2019/11/19 12:45:41 Finish parsing all file paths for "/Users/demo/Documents/test.txt"

The following file(s) has been found in path "/Users/demo/Documents/test.txt" and will be uploaded:

Example using two wildcards in one path. Here we add test_*/ to the --upload-path to upload files in more than one directory, and then we add *.jpg to add only the files from those directories with a “.jpg” extension:

Local Submission History

The application will keep track of which local files have already been submitted to avoid potential duplication in submissions. This information is kept in a JSON file in the “logs” directory under the same user folder as where the config file lives, for example:

Mac/Linux: /Users/demo/.gen3/logs/<your_config_name>_succeeded_log.json
Windows: C:\Users\demo\.gen3\logs\<your_config_name>_succeeded_log.json

Each object in the succeeded log file is a key/value pair of the full path of a file and the GUID it is associated with.

Example of a succeeded log JSON File:

{
  "/Users/demo/test.gif":"65f5d77c-1b2a-4f41-a2c9-9daed5a59f14"
}

When you run a gen3-client upload command, the client will check the succeeded_log.json log file for the files found in the provided --upload-path. If a file in the --upload-path is found in the succeeded log file, it will be skipped. For example:

~/Documents> gen3-client upload --profile=demo --upload-path=test.txt
2019/11/19 16:00:42 Finish parsing all file paths for "/Users/demo/Documents/test.txt"

The following file(s) has been found in path "/Users/demo/Documents/test.txt" and will be uploaded:
	/Users/demo/Documents/test.txt

2019/11/19 16:00:42 File "/Users/demo/Documents/test.txt" has been found in local submission history and has been skipped for preventing duplicated submissions.

In the rare case that you need to upload the same file again, the success log file will need to be moved, modified, renamed, or deleted. Alternatively, the file itself can be moved or renamed, as the information stored in the succeeded_log.json is the file’s full path.

Indexd records

When files are successfully uploaded by the gen3-client, the software service indexd creates a record for that file in the file index database, which can be accessed at the /index endpoint. For example, if the file’s GUID is 5bcd2a59-8225-44a1-9562-f74c324d8dec, enter the following URL in a browser or request it via the API to view its indexd record: https://nci-crdc-demo.datacommons.io/index/5bcd2a59-8225-44a1-9562-f74c324d8dec.

Mapping uploaded files

Files that have been successfully uploaded now have a GUID associated with them, and there is also an associated record in the indexd database. However, in order for the files to show up in the data portal, the files have to be registered in the PostgreSQL database. In other words, indexd records exist for the files, but sheepdog records (that is, structured metadata in the graph model) don’t exist yet. Thus, the files aren’t yet associated with any particular program, project, or node. To create the structured data records for the files via the sheepdog service, Windmill offers a “Map My Files” UI, which can be reviewed here.

Removing unwanted uploaded files

Before the files are mapped to a project’s node in the data model, the files can be deleted both from indexd and from the cloud location by sending a delete request to the fence endpoint /user/data/. For example, to delete the file we checked in the index above, we’d send a delete API request to this URL: https://nci-crdc-demo.datacommons.io/user/data/5bcd2a59-8225-44a1-9562-f74c324d8dec

For example, running this script will delete all the user’s unmapped files from indexd and from the storage location using the fence endpoint:

~> python delete_uploaded_files.py -a https://nci-crdc-demo.datacommons.io/ -u user@datacommons.org -c ~/Downloads/demo-credentials.json
Found the following guids for uploader user@datacommons.io: ['3d275025-8b7b-4f84-9165-72a8a174d642', '5bcd2a59-8225-44a1-9562-f74c324d8dec', '6cf194f1-c68e-4976-8ca4-a0ce9701a9f3', '956890a9-b8a7-4abd-b8f7-dd0020aaf562', '9bd009b6-e518-4fe5-9056-2b5cba163ca3']

4) Download a Single Data File Using a GUID


Files with a valid storage location in the file index database (AKA indexd) can downloaded using the gen3-client download-single command by providing the file’s object_id (AKA GUID or did).

For example, the indexd record for object_id “00149bcf-e057-4ecc-b22d-53648ae0b35f” points to a location in the GDC.

Required Flags: * –profile: The user profile specifying the api-endpoint and credentials. * –guid: The GUID (or “object_id” in Postgres or “did” in indexd) of the file.

Optional Flags: * –download-path: Specify the directory to store files in. * –filename-format: The format of filename to be used, including “original”, “guid” and “combined” (default “original”).

  • –no-prompt: If set to true, no user prompt message will be displayed regarding the filename-format.
  • –protocol: The protocol to use for file download. Accepted options are: “s3”, “http”, “ftp”, “https”, and “gs”.
  • –rename: If “–filename-format=original” is used, this will rename files by appending a counter value to its filename when files with the same name are in the download-path, otherwise the original filename will be used.
  • –skip-completed: If set to true, the name and size of local files in the download-path are compared to the information in the file index database. If a local file in the download-path matches both the name and size, it will not be downloaded.

NOTE: The “–skip-completed” option also attempts to resume downloading partially downloaded files using a ranged download. That is, if a local file with the same name exists in the download-path, but the size does not match what is in the file index, the client will attempt to resume the download where it left off.

Example Usage:

gen3-client download-single --profile=demo --guid=00149bcf-e057-4ecc-b22d-53648ae0b35f --no-prompt --skip-completed

5) Provide a Manifest File for Bulk Download


A download manifest can be generated using a Gen3 data common’s “Exploration” tool. To use the “Exploration” tool, open the common’s Windmill data portal and click on “Exploration” in the top navigation bar. After a cohort has been selected, clicking the “Download Manifest” button will create the manifest for the selected files. The gen3-client will download all the files in the provided manifest using the gen3-client download-multiple command.

NOTE: The download-multiple command supports multi-threaded downloads using the “–numparallel” option. While using this option will decrease time to download when downloading a batch of files, it is not recommended to use this option when trying to download extremely large files (50+ GB).

NOTE: If a download command is interrupted and results in partially downloaded files, the “–skip-completed” option can be used to attempt to resume downloading the partially downloaded files using a ranged download. The gen3-client will compare the file_size and file_name for each file in the “–download-path”, and resume downloading any files in the manifest that do not match both.

Example Usage:

6) Generate a metadata TSV


In order to register data files in a Gen3 data commons, the filenames, md5sums, and file_size in bytes, must be submitted as metadata. The gen3-client can help collect the values of these three properties using the gen3-client generate-tsv command.

NOTE: For most data uploaders, using the gen3-client upload command followed by mapping files in Windmill is the preferred method for uploading files. See this section of the documentation for details.

The template TSV for a data file node should be downloaded from the node’s entry page in the data dictionary and used as a template with this command. Then the wildcard character * can be used to add all matching files to the specified output tsv.

To download template TSVs from a common, open the common’s Windmill data portal and click on “Dictionary” in the top navigation bar to open the data dictionary. Template TSVs can be obtained from each node’s page in the data dictionary by clicking on the node’s name.

Template

Example Usage:

gen3-client generate-tsv --from-template=<template.tsv> --output=<output.tsv> <wildcard>

gen3-client generate-tsv --from-template=imaging_file_template.tsv --output=images.tsv \*.dcm

Adding file image-1.dcm
Adding file image-2.dcm
Adding file image-3.dcm
Adding file image-4.dcm
Generated tsv images.tsv from files *.dcm!

NOTE: In the MacOS terminal, the asterisk “*” is a wildcard character and needs to be escaped with a backslash “\”.

The output file will have the filename, file_size, and md5sum properties for each of the matching files filled in. In order to complete the TSV, fill in the other required properties, including a column of “urls” with the s3 bucket location of the files.

Example of a Complete TSV File:

read_groups.submitter_id#1	type	project_id	submitter_id	data_category	data_format	data_type	experimental_strategy	file_name	file_size	md5sum	urls
rg-1	submitted_aligned_reads	project-name	SAR1	Sequencing Reads	BAM	Aligned Reads	DNA Panel	SAR1.bam	2032590693	ba05a167e793f5c9159e468ff080647c	s3://my-data/SAR1.bam

7) How to Upload a Single Data File Using a GUID


If a data file has already been assigned a GUID via registration in a Gen3 data commons’ indexd database, then the gen3-client can be used to upload the file associated with that GUID to object storage via the gen3-client upload-single command.

NOTE: For most data uploaders, using the gen3-client upload command followed by mapping files in Windmill is the preferred method for uploading files. See this section of the documentation for details.

The GUID or object_id property for a submitted data file can then be obtained via graphQL query or viewing the data file JSON record in the graphical model of the project.

Example Usage:

gen3-client upload-single --profile=<profile_name> --guid=<GUID> --file=<filename>

gen3-client upload-single --profile=demo --guid=b4642430-8c6e-465a-8e20-97c458439387 --file=test.gif

Uploading data ...
test.gif  3.64 MiB / 3.64 MiB [==========================================================================================] 100.00%
Successfully uploaded file "test.gif" to GUID b4642430-8c6e-465a-8e20-97c458439387.
1 files uploaded.

8) How to Upload Multiple Data Files Using a Manifest


Users can automate the bulk upload of data files by providing the gen3-client with an upload manifest. The upload manifest should follow the same format as the download manifest, which is described in the previous section. Minimally, the manifest file is a JSON that contains object_id fields. The value of each object_id field is the GUID (globally unique identifier) of a data file that will be uploaded. In this mode, we assume the filenames of data files to be uploaded are the same as the GUIDs.

Example of manifest.json (Minimal):

{
  {
    "object_id": "a12ff17c-2fc0-475a-9c21-50c19950b082"
  },
  {
    "object_id": "b12ff17c-2fc0-475a-9c21-50c19950b082"
  },
  {
    "object_id": "c12ff17c-2fc0-475a-9c21-50c19950b082"
  }
}

The gen3-client will upload all the files in the provided manifest using the gen3-client upload-multiple command.

Example Usage:

gen3-client upload-multiple --profile=<profile_name> --manifest=<manifest_file> --upload-path=<path_for_files>

gen3-client upload-multiple --profile=demo --manifest=manifest.json --upload-path=upload

Uploading data ...

10) Working from the Command-line


This section contains some general notes about working from the command-line and includes information on how to set-up your command-line shell to make working with the gen3-client easier.

File Paths

When you create or download a file on your computer, that file is located in a folder (or directory) in your computer’s file system. For example, if you create the text file example.txt in the folder My Documents, the “full path” of that file is, for example, C:\Users\demo\My Documents\example.txt in Windows or /Users/demo/Documents/example.txt in Mac OS X.

Present Working Directory

After opening a shell, command prompt or terminal window, you are “in” a folder known as the “present working directory”. You can change directories with the cd <directory> command in either shell. To view your present working directory, enter the command echo $PWD in a Mac terminal or cd alone in the Windows command prompt.

You can list the contents of your present working directory by entering the command ls in the Mac terminal or dir in the Windows command prompt. These files in the present working directory can be accessed by commands you type just by entering their filenames: for example, cat example.txt would print the contents of the file example.txt in the Mac terminal if your present working directory is /Users/demo/Documents. However, if you’re in a different directory, you must enter the “full path” of the file: for example, if your present working directory is the My Downloads folder instead of My Documents, then you would need to specify the full path of the file and enter the command type "C:\Users\demo\My Documents\example.txt", to print the file’s contents in the Windows command prompt.

Updating the PATH Environment Variable

When working in your shell, you can define variables that help make work easier. One such variable is PATH, which is a list of directories where executable programs are located. By adding a folder to the PATH, programs in that folder can be executed from any other folder/directory regardless of the present working directory.

So, by adding the directory containing the gen3-client program to your PATH variable, you can run it from any working directory without specifying the “full path” of the program. Simply enter the command gen3-client, and you will run the program.

Note: In the case that you haven’t properly added the client to your path, the program can still be executed from any directory with the following command: /full/path/to/executable/gen3-client <options>. If you are working in the directory containing the executable, then /full/path/to/executable is simply ./. So the command from the executable’s directory would be ./gen3-client.

Sending Parameters to Programs on Command-line

Most programs require some sort of user input to run properly. Some programs will prompt you for input after execution, while other programs are sent this input during execution as “flags” (AKA “arguments” or “options”). The gen3-client uses the latter method of sending user input as command arguments during program execution.

For example, when configuring a profile with the client, the user must specify the configure option and also specify the profile name, API endpoint, and credentials file by adding the flags --profile, --apiendpoint and --cred to the end of the command (see configuring a profile section above for specific examples).
