 Hello I was wondering if someone has any idee as to what is happening with my .gro file.These are the first 3 atoms in my .gro file
    1URE    10C    1   0.570   0.517   0.272
    1URE    11C    2   0.555   0.365   0.285
    1URE    12C    3   0.505   0.592   0.388now these are the first 3 atoms in the .rtp file[ URE ]
 [ atoms ]
 10C    CG311   0.045   1
 11C    CG321   0.037   1
 12C    CG321   0.037   1
when I run the pdb2gmx command: echo '1' | pdb2gmx -f Uree.1.gro -vsite hydrogens -water tip3p -o vsUree.0.gro -p Uree.topI get the following error : Fatal error:
Atom 0C1 in residue URE 1 was not found in rtp entry URE with 43 atoms
while sorting atoms.
can someone pls tell my why gromacs see's the first atom as 0C1 instead of 10C? P.S. If I load the .gro file in VMD the name of the first atom is 10C and if I change in the .rtp 10C to 0C1 it works and asks for atom 1C1 and so on
