Dear all,
Hello. Following some advises from fellow amber
friends, I have re-do the setting of the input files
(prmtop and crd files) with tleap. However, the same
problem still arrise when I try to run minimization.
| Flags: MPI
getting new box info from bottom of inpcrd
peek_ewald_inpcrd: SHOULD NOT BE HERE
The system contains about 1.4M atoms with octahedron
water and ions. And the attempting minimization is
only step no. 1, therefore setting ntx=1 (default)
(not even on MD runs). I have checked the last line of
my inpcrd file and is clear that the water box is
octahedron.
Anyone has any idea on what is going on? could it be
the limited number of atoms in sander? Please help.
regards,
Yam
