Dear MNE users, I have a custom set of labels that were shared with me by a collaborator. The labels were originally mapped to the FSaverage brain. When I use mne\_morph\_labels, I am receiving the following error: ?mne warning cannot assign label file to a hemisphere? As far as I can tell, this question has previously been asked but never answered. Any advice? Thanks all! ---

Hi Sam,     Do all the label files in the source "labeldir" follow appropriate naming conventions, i.e., ending with -lh.label or -rh.label for example?

Worked like a charm. Thank you!
