These errors are typically caused by a mismatch between your version of affy and your version of affyio. Given that you note that it works fine using affy 1.12.0, this likely means you are uing an older affyio (not the one from the current BioC 2.0 release) Ben On Mon, 2007-05-28 at 16:43 +0000, Julien Gagneur wrote: > James W.

Dear Ben, would it be possible to use the "Depends" field of the DESCRIPTION in the affy package to safeguard better against such user confusions? (i.e. state the required versions of affyio etc. rather than just their name).
