RNA WTS
The DRAGEN recipe includes the recommended pipeline specific commands.
Notes and additional options
Hashtable
For DRAGEN RNA/scRNA runs, it is recommended to use the linear hashtable.
Input options
DRAGEN input sources include: fastq list, fastq, bam, or cram.
FQ list Input
FQ Input
BAM Input
CRAM Input
Mapping and Aligning
--enable-map-align true
Optionally disable map & align (default=true).
--enable-map-align-output true
Optionally save the output BAM (default=false).
Duplicate Marking
--enable-duplicate-marking true
By default, DRAGEN marks duplicate reads and exclude them from variant calling.
RNA Variant Calling
--vc-target-bed $PATH
Restrict the variants called to a target bed. For WTS, a bed file specifying the gene-coding regions should be provided to avoid calling erroneous variants in non-coding regions due to noisy reads.
RNA Quant
--rna-library-type
Set the library according to the read orientations. Set to 'A' to auto detect the correct read orientation. Alternatively select 'IU', 'ISR', 'ISF', 'U', 'SR', or 'SF'.
RNA Splice
--rna-splice-variant-normals $PATH
Optional setting list of normal splice variants that will be used filter false positive calls. The file should be a tab separated file with the following first four columns: (1) contig name, (2) first base of the splice junction (1-based), (3) last base of the splice junction (1-based), (4) strand (0: undefined, 1: +, 2: -).
--rna-splice-variant-regions $PATH
Target region bed file. Required for panels. The name of the region must be specified in the fourth column.
RNA Fusion
--rna-gf-enriched-regions $PATH
For panels, the list of enriched genes should be set, either as a list of genes or a list of regions in BED format.
