Hi Anastasia, thanks for the information.we are able to process the DTI data successfully. we had 24 subjects which crashed during either the -perp or -path stage. I viewed the alignments between the FA and the alignement segmentations (flirt and bbr alignments), which ever alignment is better. I modify the dmrirc file to use that alignment and rerun trac-all , starting at the -prep stage all but 2 were successfuly processed with my method, that the dti tracts look good in freeview i didn't realign the registration using tkregister, because the anatomies are poor and lo res, making this realignment difficult thanks again!
