Hyunjin,

The error message is not particularly informative, so I have a couple of requests to try and track this down.

1) Did the attempted optimization generate any LOG files (e.g. BondedOpt.log)? If so, please send them to me.

2) Can you rerun with "Write debugging log" (under Advanced Settings) turned on and send me any LOG files that are generated (e.g., BondedOpt.log and BondedOpt.debug.log)

3) Outside of VMD, can you run NAMD from the folder containing the configuration and temp parameter files (i.e., min-bondangles.conf, OPTTEMP.par, etc)? Something like
path/to/namd2.exe min-bindangles.conf > test.log

Thanks,
Christopher Mayne
