Dear list, I am analysing Affymetrix GeneChips of type coli asv2. I wanted to use the "annotate" package but found no appropriate annotation files in the bioc repository. I then found out about AnnBuilder, but the vignette mentions that for any species that are neither human, rat or mouse, AnnBuilder needs to be "extended". The paragraph about AnnBuilder extension is a heading with no content in that vignette (the ABPrimer). What is the status of this ? Does someone maybe have such annotation files already that i may use? (If so, could they maybe be added to the bioc repository?) Thank you for an answer, Caroline

The challenge as I understand it, is that AnnBuilder is designed to pull most of its data from NCBI and for species other than human, rat, and mouse, there tends not to be enough information available to build the required mappings between different public data resources. > The paragraph about AnnBuilder extension is a heading with no > content in that vignette (the ABPrimer).

We'd be more than happy to add such a package if one was contributed. And thanks for the reminder about the missing section in the AnnBuilder vignette. Best, + seth
