Unable to load ifo from .m file

When trying to load an pygwinc ifo object using the new infrastructure, I get the following error:

In [20]: from gwinc import Struct

In [21]: ifo = Struct.from_file('aSiModel.m')
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)

----> 1 ifo = Struct.from_file('aSiModel.m')

    355             matlab = Matlab()
    356             matlab.addpath(os.path.dirname(path))

ValueError: attempted relative import beyond top-level package

Previously, I was able to do this by running ifo = gwinc.load_ifo('aSiModel.m'). Is this user error on my part?

While testing the rest of the functionality by running the function calls that Struct.from_file, I also got the following TypeError in the extract method:

In [10]: ifo = matlab.extract('ifo')

scipy.io.loadmat doesn't like this for some reason.

@gautam.venugopalan can you attache the .m file to this report?

Attached is the .m file I was trying to load. aSiModel.m

closed with commit c86cde7e

@gautam.venugopalan I fixed the import error, but I don't currently have the matlab engine installed to debug why the .m file you supplied is not be parsed properly (although maybe it sounds like a bug in the file?). If you determine that it is a gwinc bug please open another report.
