hmtk source model error

[bigriver]

I am learning hmtk (using openquake engine 2.5) and using the hmtk tutorial on github

https://github.com/GEMScienceTools/hmtk_docs/

when i was tying to import souce model as same format below:

from hmtk.parsers.source.model.nrml04_parser import nrmlSourceModelParser

model_filename = ’path/to/source_model_file.xml ’

model_parser = nrmlSourceModelParser (model_filename)

model = model_parser.read_file ()

The program returned error with 

TypeError: read_file() takes at least 2 arguments (1 given)

by searching hmtk document, read_file has the following format, what is identifier? what i need to do to remove the error?

read_file(identifier, mfd_spacing=0.1, simple_mesh_spacing=1.0, complex_mesh_spacing=4.0, area_discretization=10.0)[source]¶

I'm seeing that the documentation mentions "identifier" in several places but doesn't explain it further than the tautological "this is an identifier".

Basically it is some sort of string that can uniquely identify the source model (e.g. "MODEL_REGION_XYZ", or even just "1234" if that is the only model are working with). There is a logic to why it is required if you are working with several different models, but most of the time it is not used.

So: model = model_parser.read_file("SOURCE_MODEL_1") should work.

Thanks,

Graeme
