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? yan

Dear Zhijin: I did run one chip. I think that is the reason. Thank you very much for your reply. I suggest you change the code that allow customer to do gcrma for single chip. For example, if I want to do several steps normalization. The first step, I would like use gc correction, then, I would like to use gcrma for single chip. But, it is just my suggestion. Thank you very much for your fast response. On Wed, October 24, 2007 5:28 pm, Zhijin Wu wrote: > I forgot to mention that if you run only one array you may run into the > problem.
