Hello, My protein is pr-DNA complex, it is identifying DNA terminus and searching for N and C in tdb file giving error. When I select -ter and specify none as termini , it still gives error saying
"There is a dangling bond at at least one of the terminal ends. Fix your coordinate file, add a new terminal database entry (.tdb), or select the proper existing terminal entry. " Please help. Error without -ter option: Processing chain 1 'B' (434 atoms, 21 residues) Identified residue DADE1 as a starting terminus. Identified residue DTHY21 as a ending terminus. 8 out of 8 lines of specbond.dat converted successfully Start terminus DADE-1: NH3+ End terminus DTHY-21: COO- ------------------------------------------------------- Program pdb2gmx, VERSION 4.6.3 Source code file: /home/sucharita/sucharita/softwares/gromacs_all/gromacs-4.6.3/src/kernel/pdb2top.c, line: 1148 Fatal error: atom N not found in buiding block 1DADE while combining tdb and rtp For more information and tips for troubleshooting, please check the GROMACS website at http://www.gromacs.org/Documentation/Errors with -ter option selecting none Processing chain 1 'B' (434 atoms, 21 residues) Identified residue DADE1 as a starting terminus.
