Hi there!

I would like to check with you why I get the following error message when I am attempting to calculate connectivity results with 3 seed ROIs:

Error using ==> nifti.create>create_each at 29

FYI, when I use each seed ROI separately or in pairs, I get results.
Also, the contrast [1/3 1/3 1/3] with the 3 ROIs works fine with the ROI-to-ROI results explorer.

Thank you in advance!

Kind regards
