Hello, I just started learning to use the Artifact Repair toolbox ( http://cibsr.stanford.edu/tools/human-brain-project/artrepair-software.html). It looks like, however, this toolbox - at least the version that I downloaded - does not fully support images with .nii extension. I noticed this while I was trying to run art_slice. In line 242: V = spm_vol(P(i-1).fname); V will only correctly map the single volume if the filename is in .img format (i.e. one hdr+img pair of files for each volume) but not if it is in .nii format. An error also occurred when I was trying to run art_movie. In line 74 of art_automask: Y = smooth3(Y); Y is a 4-dimensional data rather than a 3. Is there an easy solution to these problems? Am I using an older version of the toolbox? Thanks! Joon
