Subject: AMBER: ANAL problem

Hi all,

I need to analyse an old trajectory generated with Amber6. I use mm_pbsa
and when the script calls the anal module, it stops with the error message:

DIHEDRAL ANGLE ERROR: 9686 15444 15447 15507 15510
32 0 0.0000 0.0000

I found the same problem in the archive of the amber mail reflector but
no solution to resolve it:
http://structbio.vanderbilt.edu/archives/amber-archive/2004/0271.php

 From this message, I conclude that it exists a problem on the dihedral
n°9686 formed by atoms 5149-5150-5170-5171.
What does the dihedral code "32" mean?
My system (>50000) could be too big for anal?
I don't find any bugfix which could correct it for Amber6. Does anyone
know a solution to resolve this problem?

Thanks in advance.
