Spock
by Dr. Jon A. Christopher
Spock is a full-featured molecular graphics program developed by Dr. Jon A. Christopher while in the lab of Thomas O. Baldwin of the Department of
Biochemistry & Biophysics at Texas A&M University. SPOCK has been designed from the ground up to be powerful, flexible and most of all, easy to use.
If you are a researcher at Texas A&M Univeristy, and are interested in using SPOCK, please contact
Lisa M. Pérez about obtaining access to the code.
Running SPOCK:
chmsgi and any SGI machine that is running IRIX 6.5 or later and has chmsgi:/chem mounted
you will need to add the following line to your .tcshrc file:
setenv SPOCK /chem/spock/spockv1.0b170/system
alias spock /chem/spock/spockv1.0b170/spock
To run SPOCK, type:
spock at the shell prompt
If you login to a remote machine, to run SPOCK, you will need to use X11 forwarding when you ssh:
ssh -X username@remote_machine_name
you may have to include the -Y flag from a linux box:
ssh -X username@remote_machine_name
Trouble Shooting

Xlib: connection to "labmol4.chem.tamu.edu:0.0" refused by server
Xlib: Client is not authorized to connect to Server
Error: Can't open display:labmol4.chem.tamu.edu:0.0
You need to use X11 forwarding when you ssh to the remote machine as described
above
