TRiCoLOR logo

TRiCoLOR is an efficient command-line application capable to accurately profile tandem repeats in error-prone long-read sequencing data. TRiCoLOR works on data both from Oxford Nanopore Technologies and Pacific Biosciences sequencers and is fast enough to be used on whole-genome alignments. TRiCoLOR offers:

  1. A module suitable to identify repetitive regions de novo (SENSoR)
  2. A module suitable to profile tandem repeats (REFER)
  3. A module suitable to visualize tandem repeats (ApP)
  4. A module suitable to check the mendelian consistency of tandem repeats in trio genomes sequencing data (SAGE)

All code is open-source and hosted on TRiCoLOR's GitHub page.
