a tool for bam file QC: Qualimap

What is it? How does it work? Features

Qualimap is a platform-independent application written in Java and R that provides both a Graphical User Inteface (GUI) and a command-line interface to facilitate the quality control of alignment sequencing data.

Qualimap examines sequencing alignment data in SAM/BAM files according to the features of the mapped reads and provides an overall view of the data that helps to the detect biases in the sequencing and/or mapping of the data and eases decision-making for further analysis.
  • Fast analysis accross the reference of genome coverage and nucleotide distribution;
  • Easy to interpret summary of the main properties of the alignment data;
  • Analysis of the reads mapped inside/outside of the regions provided in GFF format;
  • Insert size mean and median value calculation and plotting statistical distribution;
  • Analysis of the adequasy of the sequencing depth in RNA-seq experiments;
  • Clustering of epigenomic profiles.
