What is the difference between GDAS software and the ABACUS program offered through JHU?
The ABACUS algorithm was developed to read our early resequencing arrays in collaboration between Affymetrix and Aravinda Chakravarti's group, principally David Cutler and Michael Zwick, at Johns Hopkins University. ABACUS is available as shareware/freeware to academic researchers through JHU. No support is available for ABACUS. The principles of ABACUS were used by Affymetrix in our development of GeneChip DNA Analysis Software (GDAS). GDAS 2.0 was developed by Affymetrix and includes a number of subsequent improvements and visualization tools. GDAS 2.0 is available through and fully supported by Affymetrix for use with the GeneChip CustomSeq Array Program.
