BUG: Input buffer size wasn't large enough.

[AMlsct]

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

I investigate this problem, and it keeps crashing at 1000 frames. Although each stack is 5400 frames, so it doesn't really make sense to me.

If you guys have any insight that I'd be very greateful!

Hi!

Just to let you know I was able to run suite2p on v0.14.0. I'll try to investigate more this error but it looks like there is an error with the indexes in tif.data()
