Hello all,
I have run bedpostx on a series of DTI scans over ~1 year, the earlier ones in stable 5.1 and latter. I'm seeing quite a lot of variability in intensity from the earlier to later versions - re-running bedpostx in 5.3 on an older scan and comparing with 5.1 yields up to 10% variation in intensity at any given voxel between versions. I've been comparing the mean_f1 images by subtracting the new - old using fslmaths. Has anyone else seen this?
Thanks, Jeff
