Dear Paul, Thanks for the reply. I had indeed looked at your toolbox (and should have mentioned this), but it appears as if whole slices are discarded which in our case will not be necessary as we really only have one or two lines affected in 2 or slices. I may try anyway. Thank you.

You can get it for SPM5 from SPM Extensions, or from our website cibsr.stanford.edu. It works for 3D Nifti formats, but it may have bugs for 4D .nii format. The noise filtering option automatically finds bad SLICES, and fixes them, and writes a logfile of what it did. Type >> help art_slice for a description of the options. Use >> art_movie to visually review how well it fixed the line artifact.
