CGHcall: Calling Aberrations for Array CGH Tumor Profiles

Bioinformatics. 2007 Apr 1;23(7):892-4. doi: 10.1093/bioinformatics/btm030. Epub 2007 Jan 31.


CGHcall achieves high calling accuracy for array CGH data by effective use of breakpoint information from segmentation and by inclusion of several biological concepts that are ignored by existing algorithms. The algorithm is validated for simulated and verified real array CGH data. By incorporating more than three classes, CGHcall improves detection of single copy gains and amplifications. Moreover, it allows effective inclusion of chromosome arm information.
