Thank you Christoph. The gmx_mpi mdrun crashed in the step_001, with the below error;
Tabulated interaction of type 'Tab. Bonds' or 'Tab. Bonds NC' with index 0 cannot be used because no table file whose name matched '_b0.xvg' was passed via the gmx mdrun -tableb command-line option. But, it worked when I added "-tableb table_b0.xvg table_b1.xvg table_b2.xvg table_a0.xvg table_a1.xvg" to the gmx_mpi mdrun, I was surprised because it had thought the -tableb is kind of default when one intend to use tabulated potential calming in case.mdp file. (gromacs2018.1). More questions; Similar to the normal atomistic simulation, I was wondering if the minimization and equalization are needed for IBI (bonded and nonbonded) prior to the sd simulation in each step? By csg_map one can map the atomistic.trr to CG.xtc, what could be the usage of CG.txc in IBI (bonded and nonbonded) then? Should the conf.gro used in IBI be correspond to the conf.gro used in the all atom simulation? To be clear, if the CG.gro used in IBI must be exactly the one obtained by mapping the AA.gro and can not be bigger than that? Can we make the CG.gro obtained by mapping twice to use it in IBI? In using gmx rdf, we usually compare a selection (-sel) like A with a reference (-ref) like B, and this means rdf_A_B.xvg might differ with the situation where we switch the reference and selection to have rdf_B_A.xvg. So, should we also consider this in for example csg_stat in setting,xml or map.xml? in other words, should we define both <nonbonded> A B </nonbonded> and <nonbonded> B A </nonbonded>? Thanks for your time in advance.
