Conn 22a permissions problem

Summary of what happened:

I installed connn22a in my groups directory on the HPC, but other people have trouble accessing it (there is some kind of permissions problem). I tried adding very permissive permissions to no avail. There are many other Matlab neuroimaging tools that I have installed in this shared directory, e.g., SPM, conn21a etc. There are not permissions problems with any of them.


conn22a vs conn21a

Environment (Docker, Singularity, custom installation):

HPC and Matlab

Does anyone have insight into the following permissions problem? Oddly, the default installation of conn21a in the same directory has no permission issue. Thoughts? What am I missing?

Hi @Dianne_Patterson,

Can you just run chmod -R 777 /path/to/conn_installation and see if that helps?


Hi Steven,

I had previously tried chmod -R ugo+rwx, but never chmod -R 777. After a couple of hiccoughs, 777 seems to have done the trick! I had not previously understood that chmod 777 behaved a little differently.

I still don’t understand what changed between the two versions of conn, but thanks for the suggestion because at least I can share the tool now!
