Affymetrix Chromosome Analysis Suite (ChAS) 3.0


Chromosome Analysis Suite (ChAS) 3.0

ChAS was developed with input from leading experts and is tailored for copy number and cytogenetics research analysis and reporting. ChAS enables you to view and summarize chromosomal aberrations across the genome. Chromosomal aberrations may include copy number gain or loss, mosaicism, or loss/absence of heterozygosity (LOH/AOH).


  • Accessing a database for storing and querying segment data and annotations either locally (by a single user) or installed on a server/common workstation (multi-person use)       
  • Displaying the entire (or relevant subset) database contents in a histogram track       
  • Comparing your current sample with segments in the database by using the segment intersections view       
  • Expanding your reporting options with the ability to export to Microsoft® Word, create paragraph-style segment tables, generate automatic report filenames, and utilize a quick export button for all graphs and tables       
  • Integrating your expression and copy number data with the Concurrent Molecular Analysis Profiling (CoMAP™) capability       
  • Checking the duo/trio Mendelian consistency of your samples for both relatedness and identification of chromosomes with higher Mendelian errors rates       
  • Automatically correcting the non-diploid status of your sample using normalization workflow for CytoScan® arrays       
  • Using the new NetAffx® Genomic Annotation file NA33.1 (Hg19), which contains updated content from DGV, OMIM®, and RefSeq
