  IN\_TRACTOGRAM IN\_TRACTOGRAM

-

  Simple comparison of tractogram by subtracting the coordinates' data.

Does not account for shuffling of streamlines. Simple A-B operations.

Differences below 1e^3 are expected for affine with large rotation/scaling. Difference below 1e^6 are expected for isotropic data with small rotation.

### positional arguments:

- IN\_TRACTOGRAM

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

### options:

- **-h**, **--help**

  show this help message and exit

- **--reference** REFERENCE
