Unknown Section in Molecule File

Hello Everyone,

I am trying to read in molecule-data via the molecule-command to my (otherwise working) lammps program.

So I do:
molecule IDF molecule1.txt

and I get: Unknown section in molecule file (…/molecule.cpp:580)
which is:

#IDF

39 atoms

Coords # ID, xyz

I figured that it is because of the Coords section (this is why I shortened the Types section) but I really do not get what is wrong about that. Even if I take the dimer molecule file from the deposit example I get this error.

I am working on a Windows machine, could that have anything to do with this problem?

Thanks for your time and Help!

Best regards

what evidence do you have for that?

the Types section) but I really do not get what is wrong about that. Even if

works find for me on Linux with the latest development version of LAMMPS.

I am working on a Windows machine, could that have anything to do with this
problem?

what LAMMPS version do you use and did you compile LAMMPS yourself or
download a binary?
