Hello, I have a problem with justRMA causing segmentation fault when an R script is ran from command line via # R --no-save < rscript The only two lines that get executed are: >library(affy) >rma <- justRMA("file1","file2","file3","file4") Then I get: Background correcting Normalizing Calculating Expression Segmentation Fault And the script aborts. When this is done from within R, it always runs fine - no errors. But if the same commands are passed as a text file - it causes segmentation fault. This seems to be happen randomly depending on the files selected and R versions. For version 1.8.1 different file combinations cause segmentation fault than for version 1.9.0. So what causes segmentation fault in 1.8.1, does not in 1.9.0 and vice versa. I tried deleting everything and installing a new version from scratch, but with the same result. Same file combinations fail for same versions, even on different machines. If anyone knows how to fix this or has an idea on how to circumvent passing commands through a file from an external script, I would greatly appreciate any advice. Thank you! Danila
