I am using Haddock 2.4 to check docking parameters between DNA and ligand . My DNA file contain Na ion and I format it as given in Haddock library but it still gives the error -
"Error in PDB file.Issue when parsing the PDB file at line 308.ATOM/HETATM line does not meet the expected format"
format of ions in my pdb file-
HETATM 307 NA+1 NA1D 101 8.118 -6.766 34.223 0.50 15.72 NA
HETATM 308 NA+1 NA1D 101 8.498 -6.164 34.656 0.50 20.12 NA
I have attached my pdb file of DNA
