[--remove_identical_streamlines]

[--precision PRECISION] [--reference REFERENCE] [-f] in_tractogram

Validate TRX file.

Removes streamlines that are out of the volume bounding box. In voxel space, no negative coordinate and no above volume dimension coordinate are possible. Any streamline that do not respect these two conditions are removed.

Also removes streamlines with single or no point. The --remove_identical_streamlines option will remove identical streamlines. 'identical' is defined as having the same number of points and the same points coordinates (to a specified precision, using a hash table).

positional arguments

in_tractogram

Tractogram filename. Format must be one of trk, tck, vtk, fib, dpy, trx.

options

--remove_identical_streamlines

Remove identical streamlines from the set.

--reference REFERENCE
