Running under docker

This page covers general information for running with docker (no cwltool etc).

Reference data

The wrapper script ds-cgpwgs.pl allows you to either specify a set of tar.gz files or a common path for all reference files.

The advantage of the shared path is that you can use a shared reference area for many containers.

To construct a valid unpacked reference area (example is GRCh37) for cgpwgs run:

$ mkdir ref
$ cd ref
$ echo 'ftp://ftp.sanger.ac.uk/pub/cancer/dockstore/human/core_ref_GRCh37d5.tar.gz
ftp://ftp.sanger.ac.uk/pub/cancer/dockstore/human/qcGenotype_GRCh37d5.tar.gz
ftp://ftp.sanger.ac.uk/pub/cancer/dockstore/human/SNV_INDEL_ref_GRCh37d5-fragment.tar.gz
ftp://ftp.sanger.ac.uk/pub/cancer/dockstore/human/VAGrENT_ref_GRCh37d5_ensembl_75.tar.gz
ftp://ftp.sanger.ac.uk/pub/cancer/dockstore/human/CNV_SV_ref_GRCh37d5_brass6+.tar.gz' \
| xargs -tI {} bash -c 'curl -L {} | tar --strip-components 1 -zx'

Once unpacked the following options will all need to be pointed to the base of the ref area:

• -reference -r
• -annot -a
• -snv_indel -si
• -cnv_sv -cs
• -qcset -qc

Run command

The following is an example of the run command for docker. It assumes the -v locations exist:

$ export CGPWGS_VERSION=X.X.X # SET ME
$ docker run -d \
--read-only --tmpfs /tmp \
--env HOME=/var/spool/results \
-v /home/ubuntu/ref:/var/spool/ref:ro \
-v /home/ubuntu/data:/var/spool/data:ro \
-v /home/ubuntu/results:/var/spool/results:rw \
quay.io/wtsicgp/dockstore-cgpwgs:$CGPWGS_VERSION \
ds-cgpwgs.pl \
-r /var/spool/ref \
-a /var/spool/ref \
-si /var/spool/ref \
-cs /var/spool/ref \
-qc /var/spool/ref \
-pl 3.65 -pu 1.0 \
-e 'MT,GL%,hs37d5,NC_007605' \
-t /var/spool/data/tumour.bam \
-tidx /var/spool/data/tumour.bam.bai \
-n /var/spool/data/normal.bam \
-nidx /var/spool/data/normal.bam.bai \
-o /var/spool/results

By default results are written to the home directory of the container so ensure you bind a large volume and set the -home variable. As indicated above the location can be overridden via the options of ds-cgpwgs.pl.
