NAMD 2.9 Replica-exchange. FATAL ERROR: Unknown command-line option +replicas

Date: Fri Jan 04 2013 - 07:53:16 CST

Hi all,

I am having an issue with replica exchange simulations.When I run the
example command located in fold_alanin.conf,using the +replicas flag
throws the error:

Charm++ fatal error:
FATAL ERROR: Unknown command-line option +replicas

I'm using the latest NAMD_2.9_Linux-x86_64-multicore-CUDA binary and
simply attempting to run on my local workstation (CPU i7 960, GPU GeForce
GTX 580, Ubuntu 12.04 64-bit).

- Is this the wrong NAMD binary or is there something else that
   I am missing here?
- Should I compile NAMD from the source ?
- Do I need any extra libraries or should I move the existing ones
   (lib/replica) to another catalogue?

I can provide any details that seem relevant. Any help regarding this
subject would be greatly appreciated!

Many thanks,
