Dear all,
I am using mm_pbsa to post-process a trajectory file made with sander
using explicit solvent and PBC (about 41000 total atoms). The script
invokes sander to calculate the
MM part, but my sistem is too big to get sander working:
 Failed to allocate memory for ipairs: 865675245 (I am using
This is because the sander input created by mm_pbsa has a cut-off larger
the system size (99999.0) and there are too many non-bonded pairs.
I am using a Fuel R14000, 512Mb
Thank you very much in advance for the reply
