Don't know about the missing interactions ... never seen this in any of the
gmx versions using Martini ...

for the error you should increase the -rdd to 1.4/1.5 nm

Dear All,

I ran a POPC simuIation in gromacs 3.3.1 with the martini force field and it ran fine. But I am getting the following error when I run it in gromacs 4.0.4. It seems there is some problem with the way the topology is built, but I cannot find out what the problem is?




A list of missing interactions:
            G96Angle of   2395 missing      1

Molecule type 'POPC'
the first 10 missing interactions, except for exclusions:
G96Angle atoms 9 10 11 global 1933 1934 1935

-------------------------------------------------------
Program mdrun_mpi, VERSION 4.0.4
Source code file: domdec_top.c, line: 341

Fatal error:
1 of the 5532 bonded interactions could not be calculated because some atoms involved moved further apart than the multi-body cut-off distance (1.2 nm) or the two-body cut-off distance (1.2 nm), see option -rdd, for pair
s and tabulated bonds also see option -ddcheck
