Ah - yes there is - the individual matrices in the mat file cannot be
larger than 4GB.  Is it possible you hit this limit?

Sorry, I only realized this when Richard Llewellyn pointed this out a
couple of weeks ago on the list:

http://scipy-user.10969.n7.nabble.com/SciPy-User-scipy-io-loadmat-throws-TypeError-with-large-files-td18558.html

The current scipy code has an error message for matrices that are too large.

Cheers,

Matthew
