Thanks for your help, it is greatly appreciated. Regards Andrew ________________________________________ From: FSL - FMRIB's Software Library [[log in to unmask]] on behalf of Anderson M.

But automated methods can be of some help, and perhaps this script could be useful to get the structure names from the atlases that are available in FSL: http://brainder.org/2012/07/30/automatic-atlas-queries-in-fsl/ It's just a wrapper for the commands "cluster" and "atlasquery".
