Hello,
I am trying to simulate a small 20 residue all atom peptide in implicit
solvent with a salt concentration of 150mM (saltcon=0.15). I have performed
these simulations using Generalized Born model and GBSA without any
problems in sander.MPI. I am now trying to use the same model with
Poisson-Boltzmann numerical calculations instead to improve my accuracy
(igb=10), but I get the following error message:
"PBSA currently doesn't work with MPI inside SANDER"
In my script I do not specify anything about surface area calculations. The
simulation works if I run non MPI sander, but it is significantly slower
and I will not be able to complete my simulations.
Is there any way around this bug? Can I use GBSA or some approximation for
the surface area terms and PB numerical calculations for the electrostatics?
Thanks.
