[BioC] GOSeq error

Hello List

I'm using GOSeq to examine the biology behind genes found to be regulated in a RNA-Seq study. One of my comparisons yields ~450 regulated genes. Attempting to run GOSeq with this list results in the following error:

Error in if (min(fv) < lower_bound) fv = fv - min(fv) + lower_bound : 
  missing value where TRUE/FALSE needed


The same script works flawlessly (or at least gives me biologically relevant answers) with other comparisons.

Could anyone shed any light on this error message? Is it simply indicative of a lack of significant enrichment?


Thanks

Iain
