Hi Chris,
Which probtrackx output are you talking about? Is it the fdt_paths files or the target-based classification results? (i.e. seed_to_<target>.nii.gz)
In the latter case, you can use the --s2tastext option, which will produce a ascii text file summarising the seed-to-target classification results.
Cheers,
Saad.

I have refined every other aspect of my scripts but get stuck at this point, resulting in processing times of 3-4 days + (17000-30000 files) purely from file reading (in matlab). I convert and handle all my dti data in array format for memory and speed (so purely value and location in seed source space (where value is >0) enabling simple reconstruction where required).
