Qualimap: evaluating next generation sequencing alignment data


Qualimapevaluating next generation sequencing alignment data



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

Qualimap examines sequencing alignment data inSAM/BAM files according to the features of themapped reads and provides an overall view of thedata that helps to the detect biases in the sequencingand/or mapping of the data and eases decision-making for further analysis.


  • Fast analysis accross the reference of genomecoverage 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.
