singularity brainvisa multiusers

Hi guys ,

I followed the instruction on https://brainvisa.info/web/download.html
and installed brainvisa 5.0.1 using singularity 3.7.3 on centos7.

I works well with root but when i use another account:

So, I changed the permission to be writable for everybody but i'm wondering if it is the correct setup for a multiuser system.

If I understand it's a "shared" install for multiple users, right ? The permission issues occur because the home directory in /casa/host/home is used by multiple users. The solution is... undocumented yet (I think), and is:
Remove the "home" directory from the shared install directory (as admin). In this situation casa-distro will create a new "container home" directory in users home directories, in ~/.local/share/casa-distro/ so that each user will get a personal directory for himself, with appropriate permissions.

Yes!!! That's it!!! Thanks
