I've tried running the standard preprocessing pipeline now twice on my data of 32 subjects with resting state scans of up to 30 minutes. I received a message both times that it had successfully completed the preprocessing, but when I click "done" to go to the next step it starts the import process. It seems to have no problem with the initial steps (1: data completeness; 2: segmentation; 3: import conditions/covariates; 4: import functional data), but when it gets to step 5 (importing ROI data), it just seems to hang. Step 4 actually took quite a long time, but it gave me a status bar telling me which subject was being imported, and I could find the file that was being slowly written during the import. With Step 5, I am not getting any sort of update on which subject it is working on, and even after waiting a few hours I cannot find any files that have been created or edited since the step began. 

I'm running Matlab 2019 R2019b with Conn 18b. 

Does the import ROI just take a really really long time and I should just wait? Or might there be some undetected error that is causing it to hang? 

Thank you,
Josh
