iTunes is the state-of-the-art computational pipeline for identifying personalized tumor neoantigens from next-generation sequencing data. With raw whole-exome sequencing data and/or RNA-seq data, iTunes calculates five important immunogenicity features to construct a machine learning-based classifier (vitroneo) to predict and prioritize neoantigens with strong in vitro immunologic effects, followed by an efficient score scheme (vivoneo) to identify neoantigens with in vivo immunologic effects.

Docker image of iTunes is at https://hub.docker.com/r/bm2lab/itunes/. See the user manual for a detailed description usage.
-
Install all software listed above.
-
Download or clone the iTunes repository to your local system:
git clone https://github.com/bm2-lab/iTunes.git
-
Obtain the reference files from GRCh38. These include cDNA, peptide; please refer to user manual for a detailed description.
iTunes has two modes, WES
mode and VCF
mode.
PairMatchDna
mode accepts WES and RNA-seq sequencing data as input, it conduct sequencing quality control, mutation calling, hla typing, expression profiling and neoantigen prediction, filtering, annotation.
VCF
mode accepts mutation VCF file, expression profile, copy number profile and tumor cellularity as input, it performs neoantigen prediction, filtering, annotation directly on input file.
You can use these two mode by:
python iTunes.py WES -i config_WES.yaml
or
python iTunes.py VCF -i config_VCF.yaml
For detailed information about usage, input and output files, test examples and data preparation please refer to the iTunes User Manual
