[BioC] GCRMA backgrounds?

[Matthew Hannah]

As far as I'm aware there is no problem with gcrma at present (it
returns no errors). I'm sure one of the authors may confirm this.

As for the 25mers, the obvious thing to take into account is that
as you increase in length it is more likely that non-homologous
probes will bind as it would be more difficult to find sequences
that are gene specific.

HTH,
