Hi Martin,
Thanks for the "Virtual Fiber Tracks for Connectivity Visualization' toolbox. However, while importing fibers using the "whole_brain_MNI_3k.trk" file, aligned to my ICBM152 template, I got this error message. Do you have any idea? Thanks
Arnaud

This function "fibers_helper.m" should be available in the folder brainstorm3/toolbox/anatomy.
https://github.com/brainstorm-tools/brainstorm3/blob/master/toolbox/anatomy/fibers_helper.m
If it is not found there: update Brainstorm and try again.
Thanks for the info Francois
