There are a few data sources for fMRI data (OpenfMRI, Functional Connectomes, ABIDE, CRCNS, etc), many of which are accessible through NITRIC.  Methods / tutorials to download, verify, and simply get started with the data are distributed here and there.

I would like a Python-based tool that has a common interface for accessing data (downloading & getting started on) from the different data sources.

Is anybody familiar with such a tool, or know of anything remotely similar?  It seems relatively simple to build, and a necessary step for getting more data scientists working with these valuable neuroimaging datasets.

Thanks!
Ben
