Hi Kara,

I had the same problems before, and exchanged opinions with John. Per
John, the current method of writing state files with absolute path is a
compromise that the VMD group made based on a number of factors. They
could have provided an option, such as saving paths relative to the
current working directory.

I interchanged state files generated from PCs and Mac laptop. I had to
manually edit the state file. It is a plain text file, and should be
easy to edit. Before John and the VMD gurus make changes to the writing
style of the state file, this should be the simplest way to cope with
state files generated from different machines. Actually you need to
modify these files if you have moved your structure files (PDB, DCD,
etc) around, too.

For PC format, you need to follow MS rules in specifying directories,
such as using double back slashes ...

Good luck!

Marc
