ACEseq Workflow

Original Author: Kortine Kleinheinz k.kleinheinz@dkfz-heidelberg.de

Current Author: Gregor Warsow g.warsow@dkfz-heidelberg.de

Description

ACEseq (Allele-specific copy number estimation with whole genome sequencing) is a tool to estimate allele-specific copy numbers from human WGS data, and comes along with a variety of features:

  • GC/replication timing Bias correction
  • quality check
  • SV breakpoint inclusion
  • automated estimation of ploidy and tumor cell content
  • HRD/TAI/LST score estimation
  • with/without matched control processing

Changelog

  • Version update 6.0.0

    • Changed the phasing routine. The program "impute2" was replaced by "Beagle". Files and tools were renamed accordingly.
