Hello Gabor,
There have a number of changes and fixes to the FEAT pipeline since 4.1 which will cause differences in cope values, although a global 10x difference does seem large. Is the entire cope image 10 times greater in magnitude, or is it only the extrema? How do the model fits and t-statistics compare?
Kind Regards
Matthew

Doing a quick check in fslview it seems that the cope file generated by version 5.0. is the correct one. Is it a known issue?
