What version of PHENIX do you have?
I would recommend using a SMILES string as input to eLBOW if possible.
In the latest version you can use
phenix.elbow --chemical-components FMN
to run the SMILES string for FMN from the PDB Chemical Components
database. It even uses the correct atom names.
In older versions you can get SMILES string from the MSDChem website.
For FMN its
