v1.3.0.b1

• Source: https://github.com/sbamin/gdc-client
• Docker: https://hub.docker.com/r/sbamin/gdc-client
• Based on gdc-client Ubuntu x64 binary at https://gdc.cancer.gov/access-data/gdc-data-transfer-tool

• In the host machine (where you've installed docker): Create or preferably mount an external disk to store sequence data, e.g., /mnt/myscratch/.

To avoid potential issues with file permissions on the host machine, avoid mounting entire home directory or path to critical data as a docker shared volume. I usually prefer creating a new directory for shared volume.

• Download and keep GDC manifest file in tsv/txt format for open access files in the shared directory.
• Save GDC token file in the same director and do chmod 600 gdc_token.key
• IMPORTANT: Make sure to pass valid (identical to host machine) user and group environment variables in docker run command else stored files may inherit root or strange user ownership.

## path where data will be stored on the host machine
export USERMOUNT="/mnt/myscratch"
cd "${USERMOUNT}"
## MAKE SURE TO GIVE PROPER USER AND GROUP IDs, matching to those of host machine
docker run -d -e HOSTUSER=$USER -e HOSTGROUP=$(id -gn $USER) -e HOSTUSERID=$UID -e HOSTGROUPID=$(id -g $USER) -v "${USERMOUNT}":/scratch sbamin/gdc-client "gdc-client download --log-file=download.log -n 4 -t gdc_token.key -m controlled_manifest.tsv"

Here, we run docker in daemon mode, mount /mnt/myscratch (supply full path and not relative) directory on the host machine to /scratch location within docker container. Then we start, gdc-client download with 4 threads and fetch controlled access data from the downloaded manifest using download key. For logging, -v does not seem to work, so using --log-file=download.log to save file in in mounted host volume.

• At the -m flag, only specify name of the manifest file, e.g., controlled_manifest.tsv and not the whole path. docker container will start with container work directory, /scratch which is mapped to /mnt/myscratch on the host machine. So, docker container would look for controlled_manifest.tsv in the mounted /scratch directory, i.e., /mnt/myscratch/controlled_manifest.tsv location on the host machine!

• For controlled access data, avoid using daemon mode with -d flag before testing that API token, gdc_token.key is working else you may end up requesting too many login requests and get blocked of further data access.
• In case of authorization failure, kill docker container using docker kill <container ID> command. Check container ID using command to check running docker processes: docker ps

• Remove -t gdc_token.key and replace -m controlled_manifest.tsv with -m open_manifest.tsv

## path where data will be stored on the host machine
export USERMOUNT="/fastscratch/foo/dump/gdc/test"
cd "${USERMOUNT}"
## MAKE SURE TO GIVE PROPER USER AND GROUP IDs, matching to those of host machine
docker run -d -e HOSTUSER=$USER -e HOSTGROUP=$(id -gn $USER) -e HOSTUSERID=$UID -e HOSTGROUPID=$(id -g $USER) -v "${USERMOUNT}":/scratch sbamin/gdc-client "gdc-client download --log-file=download.log -n 4 -m open_manifest.tsv"

docker ps
docker logs <container NAME or ID>

• To debug in case of download failure, add --debug flag. Not recommended if gdc-client download is working properly else this will increase write operations a lot!

docker run -d -e HOSTUSER=$USER -e HOSTGROUP=$(id -gn $USER) -e HOSTUSERID=$UID -e HOSTGROUPID=$(id -g $USER) -v "${USERMOUNT}":/scratch sbamin/gdc-client "gdc-client download --debug --log-file=download.log -n 4 -t gdc_token.key -m controlled_manifest.tsv"

Instead of supplying download manifest, you can supply analysis UUID, i.e., first column value of the manifest, and run multiple (prefer not to run more than 2-3 on one compute node) docker instances using one the above two command for open or controlled access data, respectively.

gdc-docker-dn-x64-el6 is a bash wrapper to start per-sample (analysis UUID) docker download instance. It's not ready for release yet, but it formats following docker run command by taking a few user-supplied arguments.

docker run -d --name 1da7105a-f0ff-479d-9f82-6c1d94456c91 -e HOSTUSER=foo -e HOSTGROUP=staff -e HOSTUSERID=1000 -e HOSTGROUPID=1001 -v /fastscratch/foo/gdc:/scratch sbamin/gdc-client:1.3.0.b1 "gdc-client download --log-file=/scratch/docker_logs/docker_1da7105a-f0ff-479d-9f82-6c1d94456c91_22Apr18_124819EDT.log -n 8 -t gdc_token.key 1da7105a-f0ff-479d-9f82-6c1d94456c91"

• PS: Valid volume mounts are required (see below) before executing gdc-client

docker run -e HOSTUSER=$USER -e HOSTGROUP=$(id -gn $USER) -e HOSTUSERID=$UID -e HOSTGROUPID=$(id -g $USER) -v "${USERMOUNT}":/scratch sbamin/gdc-client "gdc-client download --help"
docker run -e HOSTUSER=$USER -e HOSTGROUP=$(id -gn $USER) -e HOSTUSERID=$UID -e HOSTGROUPID=$(id -g $USER) -v "${USERMOUNT}":/scratch sbamin/gdc-client "gdc-client upload --help"
