Run GPU-accelerated deepvariant algorithm.

Parabricks has accelerated Google Deepvariant to extensively use GPUs and finish 30x WGS analysis in 25 minutes instead of hours. The Parabricks flavor of Deepvariant is more like other command line tools that users are familiar with. It takes the BAM and reference as inputs and produces variants as outputs. Currently, Deepvariant is supported for T4, V100, and A100 GPUs.

--num-threads

Number of threads per GPU for each call (default: 4)

--tumor-mtc

Type of multiple testing correction for tumor. Possible values are {bonf,holm-bonf,fdr}. Default value is bonf (default: bonf)

--tumor-mtc-alpha

Multiple testing correction alpha for tumor. Default value is 1.000000 (default: 1.0)

--min-cov MIN_COV

Minimum coverage for somatic calls. Default value is 7 (default: 7)

--germline

Also list germline calls in separate file (default: None)

--use-orphan

Use orphaned/anomalous reads from pairs in all samples (default: None)

--baq-off

Switch use of BAQ off in all samples (default: None)

--no-src-qual

Disable use of source quality in tumor (default: None)

--num-gpus NUM_GPUS

Number of GPUs to use for a run. GPUs 0..(NUM_GPUS-1) will be used. If you are using flexera, please include –gpu-devices too.

--gpu-devices GPU_DEVICES

Which GPU devices to use for a run. By default, all GPU devices will be used. To use specific GPU devices enter a comma-separated list of GPU device numbers. Possible device numbers can be found by examining the output of the nvidia-smi command. For example, using –gpu-devices 0,1 would only use the first two GPUs.
