[BioC] MAS problem

[Michael Barnes]

I am encountering trouble with the mas implementation in the affy
package.

> eset<-mas5(Data)
background correction:mas
PM/MM correction:mas
expression values:mas
background correcting...done.
22283 ids to be processed
|                                          |
|##########

Then it hangs.  I let it go for about 20 minutes but nothing has
happened.  According to task manager, R is still functioning.  Any
suggestions?

I get the same response when I use 

eset<-expresso(Data,normalize=FALSE,bgcorrect.method="mas",pmcorrect.method="mas",summary.method="mas")



R1.9.1
Windows XP Pro
affy 1.2.64
