trimming https://w3id.org/cwl/view/git/174f3b239018328cec1d821947438b457552724c/definitions/types/trimming_options.yml#trimming_options (Optional)
vep_pick
reference File
tumor_name String (Optional) tumor_name: String specifying the name of the MT sample

tumor_name provides a string for what the MT sample will be referred to in the various outputs, for example the VCF files.

normal_name String (Optional) normal_name: String specifying the name of the WT sample

normal_name provides a string for what the WT sample will be referred to in the various outputs, for example the VCF files.

scatter_count Integer

scatters each supported variant detector (varscan, pindel, mutect) into this many parallel jobs

synonyms_file File (Optional)
vep_cache_dir Directory
bait_intervals File
cle_vcf_filter Boolean
tumor_sequence https://w3id.org/cwl/view/git/174f3b239018328cec1d821947438b457552724c/definitions/types/sequence_data.yml#sequence_data[] tumor_sequence: MT sequencing data and readgroup information

tumor_sequence represents the sequencing data for the MT sample as either FASTQs or BAMs with accompanying readgroup information. Note that in the @RG field ID and SM are required.

normal_sequence https://w3id.org/cwl/view/git/174f3b239018328cec1d821947438b457552724c/definitions/types/sequence_data.yml#sequence_data[] normal_sequence: WT sequencing data and readgroup information

normal_sequence represents the sequencing data for the WT sample as either FASTQs or BAMs with accompanying readgroup information. Note that in the @RG field ID and SM are required.

varscan_p_value Float (Optional)
target_intervals File target_intervals: interval_list file of targets used in the sequencing experiment

target_intervals is an interval_list corresponding to the targets for the capture reagent. Bed files with this information can be converted to interval_lists with Picard BedToIntervalList. In general for a WES exome reagent bait_intervals and target_intervals are the same.

summary_intervals https://w3id.org/cwl/view/git/174f3b239018328cec1d821947438b457552724c/definitions/types/labelled_file.yml#labelled_file[]

pindel_insert_size Integer
vep_ensembl_species String

ensembl species - Must be present in the cache directory. Examples: homo_sapiens or mus_musculus

vep_ensembl_version String

ensembl version - Must be present in the cache directory. Example: 95

vep_to_table_fields String[]
annotate_coding_only Boolean (Optional)
per_target_intervals https://w3id.org/cwl/view/git/174f3b239018328cec1d821947438b457552724c/definitions/types/labelled_file.yml#labelled_file[]
strelka_cpu_reserved Integer (Optional)
varscan_min_coverage Integer (Optional)
varscan_min_var_freq Float (Optional)
vep_ensembl_assembly String

genome assembly to use in vep. Examples: GRCh38 or GRCm38

varscan_strand_filter Integer (Optional)
qc_minimum_base_quality Integer (Optional)
target_interval_padding Integer target_interval_padding: number of bp flanking each target region in which to allow variant calls

The effective coverage of capture products generally extends out beyond the actual regions targeted. This parameter allows variants to be called in these wingspan regions, extending this many base pairs from each side of the target regions.

varscan_max_normal_freq Float (Optional)
variants_to_table_fields String[]
qc_minimum_mapping_quality Integer (Optional)
filter_somatic_llr_threshold Float

Sets the stringency (log-likelihood ratio) used to filter out non-somatic variants. Typical values are 10=high stringency, 5=normal, 3=low stringency. Low stringency may be desirable when read depths are low (as in WGS) or when tumor samples are impure.

filter_somatic_llr_tumor_purity Float

Sets the purity of the tumor used in the somatic llr filter, used to remove non-somatic variants. Probably only needs to be adjusted for low-purity (< 50%). Range is 0 to 1

picard_metric_accumulation_level String
variants_to_table_genotype_fields String[]
filter_somatic_llr_normal_contamination_rate Float

Sets the fraction of tumor present in the normal sample (range 0 to 1), used in the somatic llr filter. Useful for heavily contaminated adjacent normals. Range is 0 to 1
