Hi All, We have a custom Affy chip that has some very long probesets (~300 probes). When I try to use rma on this data, a segfault is thrown, expresso() does not exhibit this problem, but is of course, much slower. Is there a built-in size restriction on the number of probes in a probeset somewhere within RMA? -Greg Gregory R.

That sounds like the problem. I'll try the development version and see if it runs. -G > > Ben > > > > > > > > On Wed, 2004-02-18 at 20:08, Warnes, Gregory R wrote: > > Hi All, > > > > We have a custom Affy chip that has some very long > probesets (~300 probes). > > When I try to use rma on this data, a segfault is thrown, > expresso() does > > not exhibit this problem, but is of course, much slower. > > > > Is there a built-in size restriction on the number of > probes in a probeset > > somewhere within RMA? > > > > -Greg > > > > Gregory R.
