This tool filter streamlines from a *.trk file based on:
- a mask;
- u-shape fibers based on a segmentation file.;
streamlineFilter -i input.trk -o output.trk <options>
-i input streamline.trk file (required)
-o output streamline.trk file (required)
-l threshold length. Streamlines shorter than a threshold will be removed.
-r reference image
-m mask image. All streamlines outside the mask will be removed. This input doesn't need to be binary, streamlines passing through voxels with intensity larger than zero will be kept.
-nu no ushape fibers. This flag will remove every streamline that starts and ends with the same segmentation label. (-m flag should input a segmentation).
-s subsampling number. It will randomly pick a subset of the streamlines in the file.
