I've just downloaded the latest version of brainstorm (available in the official website: https://neuroimage.usc.edu/bst/download.php). I followed all the instructions to install it and download it, but when I open it in Matlab (version 2018b) it gives me the the following errors (shown in the image).
I've created the output database folder as described in the instruction paying attention to not create it in the directory folder where the MATLAB code for Brainstorm is saved.
Thank you for the report, it should be fixed in the latest version. Did you also encounter this issue in Matlab version 2018b? I find it odd that I could not reproduce it. If you have more issues, please briefly describe how to reproduce them.
