Hi FSL experts, I run the tractography and I'm getting negative values in the seed_to_target file. Which doesnt make sense because " the value of each voxel within the seed mask is the number of samples seeded from that voxel reaching the relevant target mask". There can't be a negative number of samples. What can be wrong here?
Thanks,
Ps. The command im running is:
probtrackx2 -x SEED -l --xfm=FREESURFER_2_DIFF_MATRIX --meshspace=freesurfer --seedref=FREESURFER_BRAIN --stop=TARGET --opd -s MERGED -m NODIF_BRAIN_MASK --dir=OUTPUT --waypoints=TARGET --targetmasks=TARGET --os2t
