Dear developers,
I am using amber9 to run mm_pbsa calculation on a protein-ligand complex.
Using a SCALE parameter of 2 (grid space 0.5), PBSA works fine.
When I try to increase the SCALE parameter to 4 (grid space 0.25)
I have this error:
SA surface: setting up working radii
SA surface: found nonzero radii 5172
Number of SA srf points exposed 52227
SA Bomb in sa_arc(): Allocation aborted 0 0
1 0 0
I am using a fillratio equal to 4.
Looking at the amber9 code is_init.f, it seems to me that the maxarc
and/or maxarcdot have to be redimensioned to higher values.
Before doing that, I would prefer receiving a feedback from
the developers.
Thank you very much in advance
Giulio
