Hello, when I run "view(universe)", there is a warning "No PDB or VRML viewer defined".
 
I have install the vmd in the directory "/usr/local/bin". I think that it happens because
 
the environment variable PDBVIEWER and VRMLVIEWER are not set. But how can I set the variables?
 
Thank you very much.
