I think that would be a factor of 4. You might also try downsampling via the maxfilter command line via -ds 4 -nosss.

Does anyone know what to use for the downsampling_factor?
I am trying to downsample a file from 1000Hz to 256Hz
using fiff_downsample and it wants a downsampling_factor. Do I use 256 or 3.9 (1000/256)
or .256 (256/1000) ?
