RNA PIPELINE

Run GATK best practices for RNAseq short variant discovery (SNPs + Indels)

The RNA GATK pipeline process the input fastq files. The output is in VCF format.

--ref

Path to the reference file (default: None)

--in-fq

Path to the pair ended fastq files followed by optional read group with quotes (Example: “@RGtID:footLB:lib1tPL:bartSM:sampletPU:foo”). Files can be in fastq or fastq.gz format or a google cloud storage object. If no read group is provided, one will be automatically added by the pipeline. Example 1: –in-fq sampleX_1_1.fastq.gz sampleX_1_2.fastq.gz . Example 2: –in-fq sampleX_1_1.fastq.gz sampleX_1_2.fastq.gz “@RGtID:footLB:lib1tPL:bartSM:sampletPU:unit1” (default: None)

--in-se-fq

Path to the single ended fastq file followed by optional read group with quotes (Example: “@RGtID:footLB:lib1tPL:bartSM:sampletPU:foo”). File can be in fastq or fastq.gz format or a google cloud storage object. Either all sets of inputs have read group or none should have it and will be automatically added by the pipeline. This option can be repeated multiple times. Example 1: –in-se-fq sampleX_1.fastq.gz –in-se-fq sampleX_2.fastq.gz . Example 2: –in-se-fq sampleX_1.fastq.gz “@RGtID:footLB:lib1tPL:bartSM:sampletPU:unit1” –in-se-fq sampleX_2.fastq.gz “@RGtID:foo2tLB:lib1tPL:bartSM:sampletPU:unit2” . For same sample, Read Groups should have same sample name (SM) and different ID and PU (default: None)

LB tag for read groups in this run (default: None)

--read-group-pl

PL tag for read groups in this run (default: None)

--read-group-id-prefix

prefix for ID and PU tag for read groups in this run. This prefix will be used for all pair of fastq files in this run. The ID and PU tag will consist of this prefix and an identifier which will be unique for a pair of fastq files (default: None)

--two-pass-mode

2-pass mapping mode. The string can be “None” for 1-pass mapping or “Basic” for basic 2-pass mapping with all 1st pass junctions inserted into the genome indices on the fly (default: Basic)

--read-length

Input read length used to determine sjdbOverhang (default: None)

--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>. e.g. –haplotypecaller-options=”-min-pruning 4 -standard-min-confidence-threshold-for-calling 30” (default: None)

--static-quantized-quals

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

--rna

Run haplotypecaller optimized for RNA Data (default: None)

--ploidy

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

-L, --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

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

--dont-use-soft-clipped-bases

Dont use soft clipped bases for variant calling.

--ploidy PLOIDY

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

--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.
