Hallo:
Minimization of the non solvated system under GB conditions runs fine. In
contrast, the TIP3 solvated/ion-added system resists
minimization/velocityQuenching .
No indication of clashes:
lsort -unique -increasing -integer [join [measure contacts 1.4 [atomselect
top "noh"]]]
>Main< (psfgen) 36 %
It is only at 1.5A that the above command reveals a two atoms.
However, at
timestep 0.000001
maximumMove 0.000001
with
rigidBonds water
rigidTolerance 0.000001
exclude scaled1-4
cutoff 12.0
switching on
switchdist 10.0
pairlistdist 13.5 # cutoff +3.5
margin 5
1-4scaling 1.0
error arises:
TCL: Running for 1000 steps
FATAL ERROR: Low global exclusion count! (97807 vs 97818) System unstable
or pairlistdist or cutoff too small.

Thanks for suggestions
