Hi Daniel,
Thanks very much for your help. We do a 3dwarp to de-oblique the dataset. I found at all of our files pre deoblique have the same I-S axis voxel number, but the 3dwarp increases the number of voxels, and so our slice number would increase.
Now that I know why this is occurring what can I do? What are the consequences of having differing slice numbers for different subjects? Also is there anyway we can change it back to a standardized slice number for every subject or a way to leave out the de-oblique?
Thanks,
Jayna
