Project Directories

Any principal investigator (PI) may request a project directory to be shared by the research team. This project directory may be used to store data, source code, binaries, and scripts. Project directories are accessible from Minerva as


A Unix project group is also created and attached to this project.  By default, project directories are created with the project group as the group owner.   Therefore members of your project have read and write permissions. Team members must be a member of that project group to access the project directory.


To find out which Unix group owns a project directory (assume your group’s name is projectA):

$ ls -ld  /sc/hydra/projects/yourGroupDirectory

drwxrwx--- 2 48 projectA 4096 2011-03-05 12:42 yourGroupProjectDirectory/

To check your current groups, and which one is the effective group (the first in the list) use groups:

$ groups

projectA xxx projectY  projectZ

To switch to the desired effective group (it will appear first in your list) use newgrp:

$ newgrp projectY

$ groups

projectY xxx projectA  projectZ


Warning: Each time you switch to a new effective group it will create a child shell.

Project directories are not backed up.  Minerva team recommends that critical information be backed up to archival storage independently.  See TSM page  To request an increase in the size of your project directory please submit a request to
