I ran the CONN setup on a high-performance computer. The COON toolbox again did not start loading the functional images. When trying to open the NIfTI files in MRIcron I received the error message "Error in reading NIfTI header: the headers need to be at least 348 bytes.". I checked the header with load_untouch_nii.m and it looked fine. Opening the functional images with Mango viewer worked well.

So, could it be the case that CONN has the same issue with the functional images as MRIcron viewer? Is there any chance to fix this?

Best,
