haplotypecaller

This tool runs a GPU accelerated haplotypecaller. Users can provide an optional BQSR report to fix the BAM similar to ApplyBQSR. In which case, the updated base qualities will be used.

Quick Start

$ pbrun haplotypecaller \
    --ref Ref/Homo_sapiens_assembly38.fasta \
    --in-bam mark_dups_gpu.bam \
    --in-recal-file recal_gpu.txt \
    --out-variants result.vcf

Compatible GATK4 Command

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.

# Run ApplyBQSR Step
$ gatk ApplyBQSR --java-options -Xmx30g -R Ref/Homo_sapiens_assembly38.fasta \
-I=mark_dups_cpu.bam --bqsr-recal-file=recal_file.txt -O=cpu_nodups_BQSR.bam

#Run Haplotype Caller
$ gatk HaplotypeCaller --java-options -Xmx30g --input cpu_nodups_BQSR.bam --output \
result_cpu.vcf --reference Ref/Homo_sapiens_assembly38.fasta \
--native-pair-hmm-threads 16

haplotypecaller Reference

Run HaplotypeCaller to convert BAM/CRAM to VCF.

Input/Output file options

--ref REF

Path to the reference file. (default: None)

Option is required.

--in-bam IN_BAM

Path to the input BAM/CRAM file for variant calling. The argument can also be a local folder containing several bams, and each will be processed by 1 GPU in batch mode. (default: None)

Option is required.

--in-recal-file IN_RECAL_FILE

Path to the input BQSR report. (default: None)

--interval-file INTERVAL_FILE

Path to an interval file with possible formats: Picard-style (.interval_list or .picard), GATK-style (.list or .intervals), or BED file (.bed). This option can be used multiple times. (default: None)

--out-variants OUT_VARIANTS

Path of the vcf/g.vcf/gvcf.gz file after variant calling. The argument can also be a local folder in batch mode. (default: None)

Option is required.

Options specific to this tool

--haplotypecaller-options HAPLOTYPECALLER_OPTIONS

Pass supported haplotype caller options as one string. Currently supported original haplotypecaller options: -min-pruning <int>, -standard-min-confidence-threshold-for-calling <int>, -max-reads-per-alignment-start <int>, -min-dangling-branch-length <int>, -pcr-indel-model <NONE, HOSTILE, AGGRESSIVE, CONSERVATIVE>, --output-mode <EMIT_VARIANTS_ONLY, EMIT_ALL_CONFIDENT_SITES, EMIT_ALL_ACTIVE_SITES>. e.g. --haplotypecaller-options="-min-pruning 4 -standard-min-confidence-threshold-for-calling 30". (default: None)

--static-quantized-quals STATIC_QUANTIZED_QUALS

Use static quantized quality scores to a given number of levels. Repeat this option multiple times for multiple bins. (default: None)

--gvcf

Generate variant calls in gvcf format. (default: None)

--batch

Given an input list of BAMs, run the variant calling of each BAM using one GPU, and process BAMs in parallel based on how many GPUs the system has. (default: None)

--disable-read-filter DISABLE_READ_FILTER

Disable the read filters for bam entries. Currently supported read filters that can be disabled: MappingQualityAvailableReadFilter, MappingQualityReadFilter, NotSecondaryAlignmentReadFilter, WellformedReadFilter. (default: None)

--max-alternate-alleles MAX_ALTERNATE_ALLELES

Maximum number of alternate alleles to genotype. (default: None)

-G ANNOTATION_GROUP, --annotation-group ANNOTATION_GROUP

Which groups of annotations to add to the output variant calls. Currently supported annotation groups: StandardAnnotation, StandardHCAnnotation, AS_StandardAnnotation. (default: None)

-GQB GVCF_GQ_BANDS, --gvcf-gq-bands GVCF_GQ_BANDS

Exclusive upper bounds for reference confidence GQ bands. Must be in the range [1, 100] and specified in increasing order. (default: None)

--rna

Run haplotypecaller optimized for RNA Data. (default: None)

--dont-use-soft-clipped-bases

Dont use soft clipped bases for variant calling. (default: None)

--ploidy PLOIDY

Ploidy assumed for the bam file. Currently only haploid (ploidy 1) and diploid (ploidy 2) are supported. (default: 2)

-L INTERVAL, --interval INTERVAL

Interval within which to call the variants from the bam/cram file. All intervals will have a padding of 100 to get read records and overlapping intervals will be combined. Interval files should be passed using the --interval-file option. This option can be used multiple times. e.g. "-L chr1 -L chr2:10000 -L chr3:20000+ -L chr4:10000-20000". (default: None)

-ip INTERVAL_PADDING, --interval-padding INTERVAL_PADDING

Amount of padding (in base pairs) to add to each interval you are including. (default: None)

Common options:

--logfile LOGFILE

Path to the log file. If not specified, messages will only be written to the standard error output. (default: None)

--tmp-dir TMP_DIR

Full path to the directory where temporary files will be stored.

--with-petagene-dir WITH_PETAGENE_DIR

Full path to the PetaGene installation directory. By default, this should have been installed at /opt/petagene. Use of this option also requires that the PetaLink library has been preloaded by setting the LD_PRELOAD environment variable. Optionally set the PETASUITE_REFPATH and PGCLOUD_CREDPATH environment variables that are used for data and credentials (default: None)

--keep-tmp

Do not delete the directory storing temporary files after completion.

--license-file LICENSE_FILE

Path to license file license.bin if not in the installation directory.

--no-seccomp-override

Do not override seccomp options for docker (default: None).

--version

View compatible software versions.

GPU options:

--num-gpus NUM_GPUS

Number of GPUs to use for a run. GPUs 0..(NUM_GPUS-1) will be used.

--gpu-devices GPU_DEVICES

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.

Note

In the values provided to --haplotypecaller-options --output-mode requires two leading hyphens, while all other values take a single hyphen.
