Hello Bogdan,
Thanks for your reply.
I used fixed GROMACS fixed file format. In the coordinate columns, if you
have more than 4 digits before the decimal point, then you get into issue.
For validation purpose, I had rechecked this even in VMD by selecting that
particular residue and it turned out that VMD takes in only 3 digits before
the decimal.
Thanks,
Satya.
