haplotypecaller
Run a GPU-accelerated haplotypecaller.
<br>
This tool applies an accelerated GATK CollectMultipleMetrics for assessing the metrics of a BAM file, such as including alignment success, quality score distributions, GC bias, and sequencing artifacts. This functions as a ‘meta-metrics’ tool, and can run any combination of the available metrics tools in GATK to assess overall how well a sequencing run has performed. The available metrics tools (PROGRAMs) can be found in the command line example below.
You can provide an optional BQSR report to fix the BAM, similar to ApplyBQSR. In this case, the updated base qualities will be used.
# This command assumes all the inputs are in <INPUT_DIR> and all the outputs go to <OUTPUT_DIR>.
$ docker run --rm --gpus all --volume <INPUT_DIR>:/workdir --volume <OUTPUT_DIR>:/outputdir

Several original HaplotypeCaller options are supported by Clara Parabricks.
To specify the inclusion or exclusion of several haplotype caller annotations,
use the --haplotypecaller-options
option:
# This command assumes all the inputs are in <INPUT_DIR> and all the outputs go to <OUTPUT_DIR>.
$ docker run --rm --gpus all --volume <INPUT_DIR>:/workdir --volume <OUTPUT_DIR>:/outputdir
-w /workdir \

pbrun haplotypecaller \
...
--haplotypecaller-options '-min-pruning 4 -A AS_BaseQualityRankSumTest -A TandemRepeat'
...
Annotations may be excluded in the same manner using the -AX
option. There should
be a space between the -A
/-AX
flag and its value.
The following are supported options and their allowed values:
- -A

The commands below are the GATK4 counterpart of the Parabricks command above. The output from these commands will be identical to the output from the above command. See the Output Comparison page for comparing the results.
