[BioC] GOseq error

[Alicia Oshlack]

Hi Iain,

I'm not sure what this error is but how does the pwf look when you run
nullp()? Does it look like a reasonable distribution? Are you using the
Wallenius approximation? Might be worth trying with method="Sampling" and
see if you get the same error.

Cheers,
Alicia
