Hi Lily - No, you should search for dmri_pathstats in the log file
(scripts/trac-all.log) and follow the syntax for the command that you'll see
there. Only change the threshold, and potentially the output file, if you don't
want to overwrite the existing one.

Subject: [Freesurfer] dmri_pathstats segment
Hi,
I am trying to get voxel by voxel stats for fmajor on a threshold that's not
the 0.2 default because when I looked at merged nii, fmajor is constructed
correctly but on a different threshold. This is the command I used:
dmri_pathstats --intrk fmajor_PP_avg33_mni_bbr/path.pd.trk --dtbase
../dmri/dtifit --outvox new_fmajor --pthr 0.4
And I am getting in the terminal:
INFO: Rejected 0 streamlines for straying off mask
INFO: Rejected 0 streamlines for reversing direction
INFO: Rejected 940 streamlines as length outliers
INFO: Have 1460 total streamlines (min/mean/max length: 75/101/117)
INFO: Have 1460 non-truncated streamlines (min/mean/max length: 75/101/117)
Segmentation fault (core dumped)
Am I running the command incorrectly?
Thank you,
Lily
