[BioC] error message in gcrma

[yzhang at vbi.vt.edu]

I downloaded the newest version of GCRMA(2.10.0) and run GCRMA, I got the
following error message:
Error in model.frame.default(formula = y ~ x, drop.unused.levels = TRUE) :
  variable lengths differ (found for 'x')
Anyone know what cause this?
