math
Module: tractogram/math
This module performs mathematical operations on tractograms. It can be used to concatenate multiple tractograms into a single file, compute the union of multiple tractograms, or perform other operations. The available operations are:
- Concatenate: Combine multiple tractograms into a single file.
- Union: Compute the union of multiple tractograms.
- Intersection: Compute the intersection of multiple tractograms.
- Difference: Compute the difference between two tractograms.
- Lazy Concatenate: Concatenate multiple tractograms without loading them into memory.
Keywords : tractogram, math, concatenate
