Hi, amber users.

I am using amber7 to do a mm_pbsa calculation. I ran into problem when I
tried to create coordinates from MD trajector file. The error message is from
the mm_pbsa.log file is:

***********************************************************
=>> Creating coordinates
    Executing makecrd
 Something wrong with NGR 4421 4420
************************************************************

In my system, total # of atom is 31192. Total # of receptor atom is 4420 and
total # of ligand atom is 54 (from 4421 to 4474).

I used amber6 for the same trajector file and can generate coordinates. I
wandor why it is not work for amber7. Also, would you please let me know what
NGR in the above mm_pbsa.log file stands for.

My mm_pbsa.log file is in below.
