I Have been trying to use the NAMDenergy plugin in vmd to calculate Vdw and
electrostatic energies of my simulation, however upon running the plugin i
receive the following error.
FATAL ERROR: Unable to access config file namd-temp.namd
FATAL ERROR: Unable to access config file namd-temp.namd

the temporary file it is talking about is supposed to be generated by vmd
to store temp data so i am really confused as to what to do about this error
