Predict cancer epitopes from cancer sequence data
Project description
Predict mutation-derived cancer T-cell epitopes from (1) somatic variants (2) tumor RNA expression data, and (3) patient HLA type.

Commandline Arguments
Genomic Variants
You must specify at least one variant input file:
Output Format
--output-csv OUTPUT_CSV_FILENAME: Path to an output CSV file
--output-html OUTPUT_HTML_FILENAME: Path to an output HTML file
RNA Expression Filtering
Optional flags to use Cufflinks expression estimates for dropping epitopes arising from genes or transcripts that are not highly expressed.
--rna-gene-fpkm-file RNA_GENE_FPKM_FILE: Cufflinks FPKM tracking file containing gene expression estimates.
--rna-min-gene-expression RNA_MIN_GENE_EXPRESSION: Minimum FPKM for genes
--rna-remap-novel-genes-onto-ensembl: If a novel gene is fully contained within a known Ensembl gene, remap its FPKM expression value on the Ensembl gene ID.
--rna-transcript-fpkm-file RNA_TRANSCRIPT_FPKM_FILE: Cufflinks FPKM tracking file containing transcript expression estimates.
--rna-min-transcript-expression RNA_MIN_TRANSCRIPT_EXPRESSION: Minimum FPKM for transcripts
Choose an MHC Binding Predictor
You must choose an MHC binding predictor using one of the following flags: * --mhc-pan: Local NetMHCpan * --mhc-cons: Local NetMHCcons * --mhc-random: Random IC50 values * --mhc-smm: Local SMM * --mhc-smm-pmbec: Local SMM-PMBEC * --mhc-pan-iedb: NetMHCpan via the IEDB web API * --mhc-cons-iedb: NetMHCcons via the IEDB web API * --mhc-smm-iedb: SMM via the IEDB web API * --mhc-smm-pmbec-iedb: SMM-PMBEC via the IEDB web API
MHC alleles
You must specify the alleles to perform binding prediction for using one of the following flags:
--mhc-alleles-file MHC_ALLELES_FILE: Text file containing one allele name per line
--mhc-alleles MHC_ALLELES: Comma separated list of allele names, e.g. “HLA-A02:01,HLA-B07:02”
MHC Binding Options
--mhc-epitope-lengths MHC_EPITOPE_LENGTHS: comma separated list of integers specifying which peptide lengths to perform MHC binding prediction for
Misc
--padding-around-mutation PADDING_AROUND_MUTATION
--self-filter-directory SELF_FILTER_DIRECTORY
--skip-variant-errors
