I have taken the coordinate of popc.pdb (128popc+2460h2o) from Tieleman's website. I want to put my membrane protein into it, so I dig a hole in the popc.pdb and get hole.pdb. When I do grompp, the machine give this information:
Fatal error: number of coordinates in coordinate file (all.gro, 17136)
does not match topology (all.top, 15993)
before do grompp, I have done that;
cat myprotein.pdb hole.pdb >all.pdb
pdb2gmx -f myprotein.pdb -o myprotein.gro -p myprotein.top -ignh
vi myprotein.top and added
# include "lipid.itp"
# include "popc.itp' and
and rename it as all.pdb
editconf -f all.pdb -o all.gro
grompp -f em.mdp -c all.gro -p all.top -o all.tpr
I didn't know what is the difference of this two number and how to solve this problem.
Thanks for any help in advance!
