Hi Everyone, I was just talking with my PI the other day and he told me that he had an interesting conversation with one of the lead developers at affymetrix. I know there have been discussions about affy's move toward a binary format and how this will affect open source environments such as bioconductor. The developer at affymetrix said that they are moving toward open source analysis of chips. He said one of the purposes of the conference in August at Berkeley (http://eci-events.com/AffyGeneChip/) was to discuss the best way to proceed with this approach. I am not sure how the move towards a binary format will affect the bioconductor community, but I am optimistic that it will not stop the developments within bioconductor. I am going to go to the conference and see what they have to say for myself.

A binary file could facilitate getting chunks of data using random access without having to go through the whole file. For example, you can imagine at some point creating you own 'probe sets' with features that are different than those mapped by Affy. However the structure of the file MUST be publicly available.
