Dear Users ! I have a problem in generating the topology of the attached molecule as pdb.
earlier i have done using the same pdb for solvating the structure using spc
and spce water box ,
there was no such error when i do for TIP4P and oplsaa force field i got the
error
as follows
-------------------------------------------------------
Program grompp, VERSION 4.5.3
Source code file: grompp.c, line: 523
Fatal error:
number of coordinates in coordinate file (1AKI_solv.gro, 4164)
does not match topology (topol.top, 5527)
--------------------------------------------------------------------
I used the following lines to do that
pdb2gmx -ignh -ff oplsaa -f 1AKI.pdb -o 1AKI_processed.gro -water tip4p
editconf -f 1AKI_processed.gro -o 1AKI_newbox.gro -c -d 0.9 -bt cubic
genbox -cp 1AKI_newbox.gro -cs spc216.gro -o 1AKI_solv.gro -p topol.top
grompp -f sub.mdp -c 1AKI_solv.gro -p topol.top -o em.tpr
mdrun -v -deffnm em
in the grompp it says the error , how to solve this , and it comes only for
tip4p not for other water models.
thanks in advance
1AKI.pdb
