runstruct_vasp Problem

Hi,
I am new to this wonderful program and I was trying to get the runstruct_vasp code run, but it gave me an error of " gzip: /usr/local/lib/pot_lda/Ti/POTCAR.Z: No such file or directory " I have changed the ezvasp file to refer to the VASP path and also changed the pseudopotentials to refer to my current directory as I copied the POTCAR file for Ti there. Also, to be noted I am running this on a cluster system, so do I need a script file for that to run runstruct_vasp, or am I doing it correctly?

Thanks.

Perhaps make sure that your POTCAR in an a subdirectory of the current directory that is called Ti. Also, Is the file read-protected?
To debug this, just look at where the "no such file directory" is pointing you to.
It is also possible that the slave nodes of your cluster don’t see the same filesystem as the root node.
