I’m using the MATLAB 2019b for automatically preprocessing and I got this error when I used the command !mrview also other command likes mrconvert (Ubuntu 20.04)

How can I solve it?

Hi,

Seeing the date this was posted it has been a while, but I was wondering is you eventually solved this problem? And if so, do you remember how?

I’m experiencing the same issue currently.
