Hi Jenny,
Hope you've figured a solution out already, but in case you haven't (and in case future Mac users encounter this problem), I encountered a similar error due to Catalina's security settings, which are set to not allow any apps to run unless they're from the app store or an 'identified developer'. Usually you would get a pop-up with the permission error but there's a chance that you didn't depending on your computer's settings. Luckily, though there's no way to allow all SPM files through System Preferences, there [i]is [/i]a way to get your computer's firewall to ignore specific applications through the command line. Try opening up Terminal and running [b]spctl --add Downloads/spm12/* [/b]to get your computer to allow SPM - you also have to run this command with spm12/*/* etc all the way to spm12/*/*/*/*/*/* to make sure you get all of the subdirectories.
You also want to make sure that SPM is in your Matlab path - instructions for this are [url=https://sites.google.com/view/conn/resources/installation]here[/url].
Depending on the size of your scans, the error could also be due to lack of space on your hard drive - for me, a ~600MB uncompressed nifti file results in as much as 7GB of CONN preprocessing/denoising output files, so unless you're only running one or two sessions or shorter fMRI scans, 18GB is likely not going to be enough. I'd recommend trying to run just one single scan through CONN to see if you can get it to work, as this shouldn't be too large for the space on your computer.
Hope this helps!
Best,
Natalie
