Hi,

Sorry, but I am still facing problems with mm-pbsa. I increased cutres to 15
but then I had another error with memory, which I solved recompiling pbsa in
single precision (as suggested in amber list). Now I am having the following
error:

-- > 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.exp.in > mm.exp.out

The statistics.in is produced but not the statistics.out. Since I previously
increased the MAXAT variable, I really donīt know why it is giving problems
now. Do you (or anyone else) have any suggestion about how to solve this? Is
it possible that something is wrong with my input files? I am sending you my
pdb for the whole complex (created by ambpdb), in and charge files as
attachment.

Best regards
Miguel
