Does anyone have any experience with building an Annotation package for organisms other than Human, Mouse, or Rat? With AnnBuilder or any other package? In the documentation for the ABPkgBuilder{AnnBuilder} method, it states that you must specify one of the three organisms and that others are not currently supported. I am working with a custom Affymetrix Bacillus anthracis chip. Thanks, Daniel Bornman Research Scientist Battelle Memorial Institute 505 King Ave Columbus, OH 43201 614.424.3229
