Dear all,
I'm a beginner for using qm/mm md in AMBER, and I got a question as follows,
Is the qmcharge for one GLU and one ASP residue involved in the qm
region to be -2, while all the other residues in the mm region?
I found that the part of output indicated that it was -1.637
Although the calculation done without errors, I'm wondering if such adjusting is ok?
###part of the output as below
QMMM: ADJUSTING CHARGES
QMMM: ----------------------------------------------------------------------
QMMM: adjust_q = 2
QMMM: Uniformally adjusting the charge of MM atoms to conserve total charge.
QMMM: qm_charge = -2
QMMM: QM atom RESP charge sum (inc MM link) = -1.637
QMMM: Adjusting each MM atom resp charge by = 0.000
QMMM: Sum of MM + QM region is now = 0.000
QMMM: ----------------------------------------------------------------------
Thank you!
Sincerely,
yuann
