Hello

I got the following error (my command is pdb2gmx -f coord.pdb -water tip3p ) :

Warning: Number of atoms in coord.pdb is 0

Software inconsistency error:
Trying to deduce atomnumbers when no pdb information is present


My pdb file has the following structure

HEADER my molecules name
ATOM 1 5.33618975678115 -0.07916062770658 1.39429663262701 n ATOM 2 6.73371782109540 -2.15676333272371 0.62908982963763 c ATOM 3 9.03483733311025 -2.20332618463802 0.65509246122614 o ATOM 4 5.38645647191591 -4.30702600755030 -0.22693721129824 n ATOM 5 2.79934580695015 -4.52186897159807 -0.44786509349390 c ATOM 6 1.68306568299327 -6.40460311779204 -1.24068079528474 o ATOM 7 1.48545702127742 -2.26124629061096 0.37342878111953 c

The numbers are cartesian coordinates in Bohrs


The file does not follow standard PDB format, which is required by all Gromacs programs to function properly.
