[gmx-users] grompp g96angle types error

[pithevenet at free.fr]

Dear all,

I launch those commands for few models :

pdb2gmx  -f 2it7-10_bestene1mc-SC.pdb  -o 2it7-10_bestene1mc-SC.gro  -p 2it7-10_bestene1mc-SC.top -ignh -missing

editconf -f 2it7-10_bestene1mc-SC.gro -o 2it7-10_bestene1mc-SC-box.gro -d 2.0 -c -bt cubic

grompp -c 2it7-10_bestene1mc-SC-box.gro -p 2it7-10_bestene1mc-SC.top -o 2it7-10_bestene1mc-SC-min.tpr -f 2it7-10_bestene1mc-SC-em.mdp

and at the grompp command I obtain : 

checking input for internal consistency...

Generated 165 of the 1596 non-bonded parameter combinations
ERROR 0 [file "2it7-10_bestene1mc-SC.top", line 1242]:

#      PDIHS:   149
#      IDIHS:   108
#       LJ14:   436

I don't understand the meaning of: No default G96Angle types.

All my files are generated by the same way, with the same softwares, and the sames options. All the models are done by the same software so the .pdb file only the coordinates of the protein change for one model to another.

Can you help me?

Thanks,
