AMBER: molsurf.c error

Hi all,


I am still with problems with mm_pbsa calculations. The error is the
following:

-- > MAXAT=10000 exceeded
molsurf: molsurf.c:1055: is_buried: Assertion `sarg1 >= 0.0' failed.
Use of uninitialized value in multiplication (*) at
/scratch/amber8/src/mm_pbsa/mm_pbsa_statistics.pm line 1336.
Use of uninitialized value in multiplication (*) at
/scratch/amber8/src/mm_pbsa/mm_pbsa_statistics.pm line 1336.
Use of uninitialized value in multiplication (*) at
/scratch/amber8/src/mm_pbsa/mm_pbsa_statistics.pm line 1336.
    No data for 0+0 MS SURF 0

[1] Exit 134 mm_pbsa.pl mm.pbsa.in > mm.pbsa.out


As I previously increased the variable MAXAT in molsurf.c file (as said in
http://amber.ch.ic.ac.uk/archive/200404/0370.html), I
don´t understand the reason of this error. Should I change the MAXAT
variable in another file?
Does anyone know what the error with molsurf.c:1055 means and how to solve
this problem?
I think my input files are ok. I created pdb files from the unsolvated top
files and they look normal.
Here is mm_pbsa.out:
