## loopmodel.get_loop_model_filename() — get the model PDB/mmCIF name

`get_loop_model_filename(sequence, id1, id2, file_ext)`

> This routine returns the PDB or mmCIF file name of each generated loop model, usually of the form `'foo.BL000X000Y.pdb'` (where sequence=foo, id1=X, id2=Y, and file_ext=.pdb). You can redefine this routine if you don't like the standard naming scheme. For typical loopmodel usage, id1 is the loop model number, running from loopmodel.loop.starting_model to loopmodel.loop.ending_model, and id2 is the comparative model number, running from automodel.starting_model to automodel.ending_model.
