[gmx-users] simulation of protein in presence of ATP

[nikhil damle]

Hi,
 
    We can use max 4 coloumns for naming atoms. But .rtp file has 5 coloumn atom names (AO1PG etc) That i modified to 4 letter name. But now the error is "atom N not found in residue 1ATP while combining tdb and rtp"

You've broken the PDB format, which encodes the information in fixed-column style. See http://www.wwpdb.org/documentation/format32/v3.2.html
