Integrative analysis of copy number alterations

CNApp represents the first web tool to perform a comprehensive and integrative analysis of copy number alterations (CNAs) in a user-friendly interface. The software uses segmented data from either aCGH, SNP-array, whole-exome sequencing or whole-genome sequencing to assess sample profiles and CNA levels, establishing associations with molecular and clinical features.

About CNApp

CNApp has been developed using Shiny R package (version 1.1.0), from R-Studio, and code is freely available at GitHub.


  



CNApp can also be downloaded and installed as local tool by following instructions specified in the README file, in the GitHub account.
