Dear Users, Performing membrane simulations using charmm36 ff. The Protein/membrane system is constructed using charmm-gui [POPC] . The system was then used in gromacs 2016.4 for simulation . Following the simulation tutorial,
*gmx pdb2gmx -f KALP-15_princ.pdb -o KALP-15_processed.gro -ignh -ter -water spc* NH2 and COOH were chosen as terminals. But bad luck its shows a fatal error. *fatal error:* *There were 49308 missing atoms in molecule Protein if you want to use this* *incomplete topology anyhow, use the option -missing* All the missing atoms were only hydrogen. the water model was then changed to tip3p, even the error prevails. Why the ignh flag doesn't work here? Can I go with -missing? Thank you -- *Regards,* *Rahul Suresh* *Research Scholar* *Bharathiar University* *Coimbatore* -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
