The gen3-client provides an easy-to-use command-line interface for uploading and downloading data files to and from a Gen3 data commons. An example of a gen3 data commons portal is NCI's Proteomic Data Commons.

• gen3-client Main Site

• Module Name: gen3 (see the modules page for more information)
• gen3-client cannot be used on Biowulf
• The client requires an API key that the user must setup with the target gen3 data commons portal before uploading or downloading data. This key is stored as a named profile (such as "demo" used in examples below). See this documentation for more information.

Helix is a dedicated interactive data transfer node. Therefore, if you wish to use the gen3-client interactively, it is recommended that you do so on helix. Sample session (user input in bold):

[user@helix ~]$ module load gen3

[user@helix ~]$ gen3-client upload --profile=demo --upload-path=test.txt 
2020/05/18 12:45:41 Finish parsing all file paths for "~/test.txt"

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

2020/05/18 12:45:41 Uploading data ...

You can include your gen3-client commands in a batch script and submit from biowulf. For example, create a batch input file (e.g. gen3.sh) like so:

#!/bin/bash
set -e
module load gen3
gen3-client download-single --profile=demo --guid=00149bcf-e057-4ecc-b22d-53648ae0b35f --no-prompt --skip-completed

Submit this job using the Slurm sbatch command.

sbatch [--cpus-per-task=#] [--mem=#] gen3.sh

Create a swarmfile (e.g. gen3.swarm). For example:

gen3-client download-single --profile=demo --guid=8f4481b1-c8c9-4db2-a48d-ab0c1097a950 --no-prompt --skip-completed
gen3-client download-single --profile=demo --guid=494a69be-4295-46bd-aa48-4dfedbb6f545 --no-prompt --skip-completed
gen3-client download-single --profile=demo --guid=5760f226-cf57-4025-9995-84f4d827c082 --no-prompt --skip-completed
gen3-client download-single --profile=demo --guid=8398df6a-63eb-4946-acb7-cc6f31b97915 --no-prompt --skip-completed

Submit this job using the swarm command.

swarm -f gen3.swarm [-g #] [-t #] --module gen3
