Hi,

I'm saving a large batch of data using savemat and although I get no errors, the files produced are not readable for either matlab or scipy. Is there a limit on file size?

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-Typ... The current scipy code has an error message for matrices that are too large. Cheers, Matthew
