marc,

you could easily postprocess the state files with a program like
sed to get the desired effect. try,

sed -e "s@${HOME}/@./@" saved_state.vmd > fixed_saved_state.vmd

to remove the home directory part or

sed -e "s@${PWD}/@./@" saved_state.vmd > fixed_saved_state.vmd

to remove the current path or just replace the ${...} part with
any string you like to remove from the pathname. this is not
totally safe, but should work in many cases.

best regards,

        axel.
