Segfault in affy:rma() with custom chip
... 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 somewhe ...

Of course, it makes sense to split the data up in some s ...
