[Mne_analysis] mne-python

[Graves, William]

Hi Alex,

Thanks very much for your help. I have another question that I feel is very basic, but I'm still finding my legs with python and I can't yet seem to figure this one out on my own. In the "Access raw data" section of the mne-python page, the command:

data_path = sample.data_path()

downloads the sample dataset from MGH. But my question is, if I have already downloaded it, how do I set the path to recognize where it is currently located, rather than having to download it again? It looks like this function comes from the "__init__.py" script in the "mne-python/mne/datasets/sample" directory, but in spite my trying to parse it I still can't seem to figure it out.

Thanks,
Will
