Inputs

ID Type Title Doc
vep_pick
reference File
tumor_bam File
normal_bam File
vep_plugins String[] (Optional)
roi_intervals File
scatter_count Integer (Optional)

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

synonyms_file File (Optional)
vep_cache_dir Directory
cle_vcf_filter Boolean (Optional)
varscan_p_value Float (Optional)
tumor_sample_name String
normal_sample_name String
strelka_exome_mode Boolean
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[] (Optional)
annotate_coding_only Boolean (Optional)
filter_minimum_depth Integer (Optional)
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)
filter_mapq0_threshold Float (Optional)
varscan_max_normal_freq Float (Optional)
variants_to_table_fields String[] (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.

readcount_minimum_base_quality Integer (Optional)
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

readcount_minimum_mapping_quality Integer (Optional)
variants_to_table_genotype_fields String[] (Optional)
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
