Hi there,
this is a very old issue for me at lest and I still get error running a remd
simulation using restraints for ion. I am using gmx4.0.7
This is my input:
; Distance restraints
disre = simple
disre_weighting = equal
disre_fc = 1000
and in topol.top
[ distance_restraints ]
; ai aj type index type' low up1 up2 fac
957 309 1 0 1 0.18 0.20 0.25 1
957 338 1 1 1 0.18 0.20 0.25 1
957 701 1 2 1 0.18 0.20 0.25 1
957 733 1 3 1 0.18 0.20 0.25 1
956 149 1 4 1 0.18 0.20 0.25 1
956 185 1 5 1 0.18 0.20 0.25 1
956 417 1 6 1 0.18 0.20 0.25 1
956 462 1 7 1 0.18 0.20 0.25 1
So all different restraints. My input run is:
#PBS -l nodes=120
mpirun mdrun_d -s remd -v -deffnm remd -multi 5 -replex 5000 -npme 8 -dd 4 4 1
and immediately I get:
Program mdrun_d, VERSION 4.0.7
Source code file: disre.c, line: 143
Fatal error:
Time or ensemble averaged or multiple pair distance restraints do not work
(yet) with domain decomposition, use particle decomposition (mdrun option
-pd)
That's strange since I am not neither using time nor ensemble averages nor
multiple dist restraints.
thansk in advance for any help
and

Oggetto: Re: [gmx-users] Martini parameters for monoolein
I do not know what is the structure of monoolein :((
Then it is strongly possible that OH-C-C-OH is best represented
by the P4 particle type. But it might not be that simple :))
you should once your (first) topology made try it out and compare
to as much data you can find ... experimental and from atomistic
simulations ... that should include dynamics, structure et
thermodynamics ...
have fun,
XAvier.
