[Mne_analysis] IOError: 2GB file size limit reached. Support for larger raw files will be added in the future.

[Lau Møller Andersen]

Dear Eric and Alex

Thanks for your answers. I now understand that it is not a simple issue.
The files themselves are not greater than 2.0 GB, but because I have multiple recordings per subject, I read them in as a list. The only reason that I ask is that I would like to save the filtered file (i.e. the one that is greater than 2.0 GB, because it is a list of raw files).

The way I work around it now, is simply to save the epoched files and working from there. The only annoying thing is, if/when I realize that I need to do something different for creating the epochs, then I need to do the time-consuming process of filtering again. But I can live with that.

Thanks again for a wonderful python toolbox.

Best

Lau

> It is challenging because the FIFF file format is not designed to handle files larger than that. Adding support for it would require redesigning and rewriting the I/O code fundamental to data analysis, and would likely break backward compatibility with many tools. AFAIK nobody is actively working on the issue.
