Dear Calros,
Thank you for your response.
I'm reading Amber8 manual on page 147 (Content of the ouput files)
carefully.
I think if I set repdrd=1, I can get mdcrd files containing data for a
particular
replica( continuous trajectory in phase space but discontinuous in target
temperature) So, can I choose any one of the mdcrd files at ramdom if I
will analize the trajectory sampling multiple temperatures?

Actually I've got the following error message.
Unit 8 Error on OPEN: INIT.top.005
Why do I need INIT.top.00X files??
Also I've got 16 md.out files but nothing is written in these files. And I
couldn't get mdcrd files and mdrst files.

this is described on page 147 of the Amber8 manual.
the repcrd variable controls what is in your output files.
for the -rem 0 problem, you need to be more specific
that just saying it failed. That doesn't give me enough information
to help.
