[gmx-users] test molecule insertion

[Simon Poblete]

Hi
I have trouble inserting molecules for test particle insertion (with 
atoms there is no problem at all).
I have defined my conf.gro, topology and index files, but it keeps 
saying that
"Number of atoms in trajectory (7000) is not equal the number in the run 
input file (7005) minus the number of atoms to insert (1)"
How can I define the number of atoms to insert?

greets
