it looks like that something failed after successful segmentation while saving ROI information. The error message points to that there is no ROI field in your xml-files. I would try to preprocess these subjects again and would check for potential error messages.

>Does anyone know why this is happening? I checked the files and for some ROIs there are NaNs included, which, I could imagine, is causing the error. Is there any way to fix this or extract ROI values for the remaining Rois or would I have to discard these subjects from further analysis? And what is causing the NaN (Quality check was fine for the data)?
