rna_gatk Reference

Run the GATK Best Practices pipeline for RNA-seq data from FASTQ to VCF.

Input/Output file options

--ref REF

Path to the reference file. (default: None)

Option is required.

--in-fq [IN_FQ [IN_FQ ...]]

Path to the pair ended FASTQ files followed by optional read group with quotes (Example: "@RGtID:footLB:lib1tPL:bartSM:sampletPU:foo"). Files must be in fastq or fastq.gz format. 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 [IN_SE_FQ [IN_SE_FQ ...]]

Path to the single ended FASTQ file followed by optional read group with quotes (Example: "@RGtID:footLB:lib1tPL:bartSM:sampletPU:foo"). The file must be in fastq/fastq.gz format. All sets of inputs should have a read group; otherwise, none should have a read group, and it 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)

--genome-lib-dir GENOME_LIB_DIR

Path to a genome resource library directory. We assume that the indexing required to run star has been completed by the user. (default: None)

Option is required.

--knownSites KNOWNSITES

Path to a known indels file. Must be in vcf/vcf.gz format. This option can be used multiple times. (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)

--output-dir OUTPUT_DIR

Path to the directory that will contain all of the generated files. (default: None)

Option is required.

--out-recal-file OUT_RECAL_FILE

Path of the report file after Base Quality Score Recalibration. (default: None)

--out-bam OUT_BAM

Path of output BAM file. (default: None)

Option is required.

--out-variants OUT_VARIANTS

Path of 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.

--two-pass-mode 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 READ_LENGTH: Input read length used to determine sjdbOverhang. (default: None)
--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".

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)

--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

The --in-fq option takes the names of two FASTQ files, optionally followed by a quoted read group. The FASTQ filenames must not start with a hyphen.

Note

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