Thanks Justin. So, I've understood how to calculate the number of coordinates. That in the topology file matches the amount I calculated (as per how you just taught me).
I want to put 2 proteins in the same box. I did this by changing the topology files of the respective proteins to itp. Then a new top file was made in which the itp files were included. I pasted the contents earlier. After this, performed editconf separately on each .gro file and combined them together. then I solvated them. Right before neutralising using genion, while using grompp to get the tpr file is where the error about the mismatch happens. How can I solve this? I've tried making sure my topology file is updated at every stage.
