An acceptance ratio of 0.2/0.3 is normally best. The problem with high
acceptance ratio is that it means that a large portion of the exchanges are
just back and forth exchanges between consecutive exchange and are thus
disturbing the system more that actually helping sampling.
I do not know
Okay Sir, I will try two-three combinations this time and will report back
to you ...

You have to convince yourself, not me :)) But I can give you my opinion …

Dear Sir,
Here's the result of three different runs :
Temperature distribution for three trials
Repeat-1 280 298 317 337 359 382 406 432 460 489 520 554 589 627
Repeat-2 280 299 319 340 363 388 414 441 471 503 536 572 611
Repeat-3 280 300 322 345 370 397 426 457 490 526 564 605 649

Sorry to ask this simple question but how to read the replica_index and
replica_temp files. I tried to search a lot but didn't find any
information. As I have concatenated all log files and demuxed them. Here's
first 10 lines from both files:-
replica_index:
0 012345
They show which structure is in which ensemble, and the inverse. Look at
the exchange events reported in the .log files and work out which is which.

The plots that I showed in my last mail were for all replicas. I tried
plotting the first 500 ps of replica_index and replica_time files. I think
the plots look fine, and there could be problem with the plotting tool .
Here the link for both files ,
The interval between the exchange trial affect the efficiency of REMD but not
the the exchange ratio (at least in principle).
In you case I am not sure what the plot are showing! Are these showing all the
replicas? what are the units?

You need to increase the temperature gaps indeed if you want acceptance ratio
~0.2/0.3. But again this won't work with the water …
It is not clear what happens in your index file but probably a problem from
grace to plot so many points … you can try to increase the Max drawing path
length in
Dear Sir,
Here's the result for the REMD trial with large temperature gaps.
