pVACtools is a cancer immunotherapy tools suite consisting of the following tools:
A cancer immunotherapy pipeline for identifying and prioritizing neoantigens from a VCF file.
A cancer immunotherapy pipeline for identifying and prioritizing neoantigens from a FASTA file.
A tool for detecting neoantigens resulting from gene fusions.
A tool designed to aid specifically in the construction of DNA-based cancer vaccines.
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 3.1.1¶
This is a bugfix release. It fixes the following problem(s):
--exclude-NAsflag was not being passed along correctly to the main pipeline and didn’t have any effect on downstream filtering.
The aggregate report creation step had some inefficiencies which caused its runtime to be much longer than necessary.
An unneeded import statement for the PyVCF package had the potential to cause errors while running the pVACseq pipeline.
New in Version 3.1¶
This release adds the following new features:
When running the pipelines with the
--netmhc-stabflag enabled, the
NetMHCstab allelecolumn now also reports the distance of the NetMHCstabpan allele when that allele is not identical to the
HLA Alleleof 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
