Subject: Modifying a Tcl script
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

Hi All,

I wish to use the ca-dist script to get the CA-CA distances for a
molcule. The script plots out the distances beautifully, but I
would like to calculate the difference between the distances in
one molecule and the distances in a second.
Thus it would be really useful to have output in some tabular
form, which I can then plot with another program and manipulate
(for difference maps etc). I really don't know much about Tcl, so
was hoping someone could suggest to me how this could be done
simply i.e what line(s) I would need to add to send the
information in the "dist" 2D array to an external file.

Any help would be much appreciated! Please reply to me directly
as I am not subscribed to the VMD-L mail list.
