Dear FSL experts, I have a binary brain mask of a certain brain structure. Is there a way to expand this mask by one voxel on each axis/side, e.g. by using fslmaths or something else? Many thanks! /Ben ######################################################################## To unsubscribe from the FSL list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=FSL&A=1
