I'm trying to save a mask of the posterior cingulate cortex, but every time I try I get the following error message: 

11-May-2020 21:01:25 | FATAL | wfu_pickatlas.m | MException thrown. Stack follows:

I've tried saving it in multiple different location, but I get the same error message everytime. I'd appreciate any help I can get.

Hi, did you ever find a solution to this? I am having the same problem when I try and dilate the masks, despite the software working fine a couple of months ago. I am not sure what has changed to result in it no longer working.

Thanks,
