Memory error reading raw files

External Email - Use Caution

Hi!
I'd like to preload raw-fif files (~40 min recording, sample rate 5000 Hz,
10.2 GB) but it seems I'm running out of memory (RAM 16GB, 2x8 GB). Do I
simply need more memory or is there any other way to tweak the loading of
the raw files?

Best,
Karin

hi Karin,

loading the file in memory will double the size as we do computations
in double precision.

I would see if you can use preload=False on read. The only thing that
can be problematic
is filtering which requires preload=True. In this case, I would
process data by chunks. You can
use the raw.crop method for this.

Or you can use memmapping by passing a filename string to `preload`, which
will be used for temporary storage.
