Hi - you can use a hidden option called “—savepaths” which will output a, ASCII text file with all the coordinates (can be quite large if you run many streamlines). The format is: #N1 x y z x y z x y z x y z #N2 x y z x y z x y z x y z … Cheers, Saad ------------------------------------------------------------------ Saad Jbabdi, PhD Associate Professor MRC Career Development Fellow FMRIB Centre, University of Oxford, John Radcliffe Hospital, Oxford, OX3 9DU, UK. tel (+44)1865-222466 (fax 717) http://www.ndcn.ox.ac.uk/team/saad-jbabdi On 20 Apr 2016, at 16:48, Jackson Smith <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hi Saad, I'd love to get individual streamlines out of probtrackx2, as you can in MRtrix ; that is, I'd love a series of coordinates showing exactly where each streamline went. I've tested your suggestion of running probtrackx2 using --verbose==2. However, I saw no streamline coordinates being printed to the terminal window. There was an additional file in the output directory called "particle0", but this was empty (0 bytes). Have I done something wrong, or misinterpreted the discussion? Can probtrackx2 produce this kind of data? Best wishes, Jackson
