Re: [ESPResSo-users] VMD Error

that is a strange problem with your Tcl installation or system, not Espresso 
and for sure not VMD.

What happens in prepare_vmd_connection is an "info hostname”. However, the 
traceback says that the command executed was actually “info address@hidden, 
which then complains that the given parameter is address@hidden:

As apparently Espresso interpreted the script up to this command, the 
interpreter seems to work fine otherwise, so maybe something with the hostname 
command is deeply broken on your system. That you can try by directly invoking 
tclsh and trying “info hostname”.
