pVACtools

pVACtools is a cancer immunotherapy tools suite consisting of the following tools:

pVACseq

A cancer immunotherapy pipeline for identifying and prioritizing neoantigens from a VCF file.

pVACbind

A cancer immunotherapy pipeline for identifying and prioritizing neoantigens from a FASTA file.

pVACfuse

A tool for detecting neoantigens resulting from gene fusions.

pVACvector

A tool designed to aid specifically in the construction of DNA-based cancer vaccines.

pVACview

An application based on R Shiny that assists users in reviewing, exploring and prioritizing neoantigens from the results of pVACtools processes for personalized cancer vaccine design.

New in Release 3.1.2

This is a bugfix release. It fixes the following problem(s):

• It fixes an issue with parsing class II IEDB output files when running pVACfuse or pVACbind, which resulted in the wrong binding prediction scores being associated with certain epitopes.

• It adds missing import statements to pVACvector.

New in Version 3.1

This release adds the following new features:

• When running the pipelines with the --netmhc-stab flag enabled, the NetMHCstab allele column now also reports the distance of the NetMHCstabpan allele when that allele is not identical to the HLA Allele of the original result.

• When running the pipelines with a set of individual class II alleles, the pipeline now also auto-generates valid combinations of these alleles so that users no longer need to explicitly provide these combinations.

This release also fixes the following problem(s):

• Some class I alleles are not supported by NetMHCstabpan and will lead to an error when attempt to make predictions with them. This release will skip such alleles for the stability prediction step.

• For very large result sets the filtering steps would stall or be killed because the steps would run out of memory. This release fixes this issue.

• This release adds better handling of timeout errors while running
