[gmx-users] merging and renumbering topology atoms

[Stud_Psychopharm]

Dear christoph,
Even I had the same problem when doing simulations with non-bio 
molecules. Instead of getting the information from PRODRG, you can 
calculate the charges,bond angle,and bond lengths by using "gamess" or 
any other software or can be done manually. Then give all those 
informations in gromacs topology file by manuplating ffgmx.rtp and 
ffgmxbon.itp files. it worked out for us.
All the best
