[gmx-users] how to use demux.pl for REMD analysis

[N-J.M. Macaluso]

Hello,

     I've been reading all of the archived questions on the analysis of 
REMD in Gromacs, and I'm still a bit confused. It appears that the first 
step is to use the demux.pl script to demultiplex the REMD trajectories. 
How to use this script, and what exactly this is supposed to accomplish? 
After this is finished, how do I trace the temperature evolution of a 
single replica?

Thanks,

Max Macaluso
