BUG: Input buffer size wasn't large enough.

Start with suite2p/io/tiff.py, especially tiff_to_binary and read_tiff, following the traceback to the ScanImageTiffReader data call. Reproduce the GUI conversion with the reported TIFF inputs and determine why the input buffer is insufficient; done means the conversion completes without this exception.

Describe the issue:

Hi,

I'm currently using the latest version of suite2p. When I try to run from the GUI, I end up with this error message. Could you help me? I really have no idea what's <<Input buffer size wasn't large enough.>> means... I'm trying to process 12 files of 1.5Gb each. I was wondering if it was not due a RAM problem, but even with only 2 files the problem remains...

Thank you!

Antoine
