Getting Building Access and Room Keys

CBCB is located on the 3rd floor of The Biomolecular Sciences Building identified on campus maps as Building #296. The building is secure and access is gained by either using your UM ID card, guest card or entering the 3-digit code of the person you to visit at the call box on the right side of the front door.

Contact the Center Coordinator, Denise Cross, about gaining card access to the building. She will need the following information:

  • An notification email from your sponsor/adviser
  • Your Name
  • Your 9 Digit University ID number
  • Your Contact email

Along with your assigned space and phone numbers, the coordinator will send your information to UMIACS Coordinator Edna Walker who will contact campus security to add you into their system. Note: clearance usually takes a number of days, so contact the coordinator as soon as possible.

If you prefer not to send your information through email feel free to contact the coordinator in person.

You must get your key from the coordinator in person.

Understanding the Layout of Available Resources

When you first log into a server (eg., you will probably be placed in one of the following personalized directories:

  • /fs/wrenhome/yourUserName/
  • /nfshomes/yourUserName/

nfshomes has a limit on available disk space (in the double digit MBs) while wrenhomes allows you the more freedom. Therefore you should use wrenhomes for your personal work files, but should be very mindful of how much space you are using and how much free space remains. For large amounts of data, you should use one of the following (after first checking with your sponsor).

For a list of our Disk Storage and amount of available space left on each one, see

Configuring Your Home Directory and Shell

We import common settings files that set our path variables to include commonly shared software repositories.

As a start, add the following line to the top of the file called ".bashrc" located in your home directory (/nfshomes/username/):

. /fs/sz-user-supported/share/dotfiles/bashrc.cbcb

This will import the common bashrc.cbcb file into your own bashrc file every time you log in.

Now add this line to your ".bash_profile" file, also located in your home directory:

. ~/.bashrc

This will import your personal bashrc file every time you log in. Now you should have access to most of the locally installed software like "blastall" and "AMOS."

If you want to add any addition commands to your bashrc file, such as setting your default text editor to "vim" or formatting the output of bash commands (eg. "ls"), add the appropriate commands after the imported common files as shown in this example:

. /fs/sz-user-supported/share/dotfiles/bashrc.cbcb

alias vi='vim'
alias ls='ls --color'

If you decide you want to change the settings in the common bashrc.cbcb to better suit your personal needs, then please copy and paste its contents into your personal bashrc file. Do not modify the common bashrc.cbcb file as it will affect everyone's environment. Also check back periodically as people may add common paths for new software.

If you have any other problems, contact staff [at] or your PI.
