Hi,
I have tried to run a FEP calculation. Below is my input file.
memory total 1500 Mb
start dutch
permanent_dir ./perm
scratch_dir /tmp
md
system dutch_neb
cutoff 1.5 qmmm 1.5
noshake solute
isotherm 0 298.15 anneal 0 3
equil 5000
record rest 1
mwm 4000
end
qmmm
print low
nsamples 1000
ncycles 10
end
set qmmm:fep_geom dutch_neb-s.xyzi dutch_neb-e.xyzi
set qmmm:fep_esp dutch_neb-s.esp dutch_neb-e.esp
set qmmm:fep_lambda 0.0 0.1
set qmmm:fep_deriv .true.
task qmmm dft fep
However, after a while the calcalution was aborted with the following error.
Total number of active Bq charges 3711
frozen_density,esp T T

using old esp charges
qmmm_bq_data_load Failed bq_pset 0

This type of error is most commonly associated with calculations not reaching convergence criteria

I'm wondering what this error implies. I have run 9 pairs of beads (there were total 10 beads) and all of them exited with the same error.
Any advice is really appreciated.
