Hi Natalia, the images in 5.0 are not in the same voxel space across time. Probably that is what's causing your problems. In 5.1 they are all resampled and processed in the subjects' template space. So you cannot simply open stuff on top of each other with 5.0 data. However, surfaces are in vertex correspondence even in 5.0 and therefore I expect long_mris_slopes to work on 5.0 data. long_stats_slopes should also work with 5.0 data as the stats files should not have changed too much, but who knows.
