          Have you tried Bioconductor (www.bioconductor.org)? I haven't seen any replies to your question, and I know next to nothing about microarray data. I understand that Bioconductor specializes in microarray and related data, has a listserve, etc.

	  hope this helps,

If I treat the dose level as a continuous variable, how can I use ANCOVA to do gene selection? (I mean to select those genes that response to different level of doses differently?). Thank you very much!
