Sir,
Thanks for the suggestions and time.
I already had a look into the output file(fib_restwt.out), and It is reading the both the restraints, and I have also changed the &wt Type.
Regards
Priya

the file fib_restwt.out shows that sander read and understood the
restraint mask, and applied it to 1434 atoms.
it also read 1 restraint from your disang file.
so- I don't see a problem. can you clarify what you think is going wrong?
also, there is no need to put REST in the weight change section, since
you are not changing it.
