Sample Overlap equal to 1

[cburik]

Hi,

I'm using the sample overlap function while doing a meta-analysis on two files and I'm getting an odd result.
The estimated sample overlap is equal to 1, when I'm sure it shouldn't be.

best,

Casper

Any chance we could use your data for debugging purposes?

Sure, where can I send it?

We could maybe setup an SFTP or a Dropbox file request (as long as the data is less than a few TB.) Shoot me an email at [email protected] and we'll figure something out.
