Differences between decimater utility and Python
Posted: Fri Feb 22, 2019 7:18 pm
The decimater utility seems to be doing something beyond simple decimation, but we can't find further documentation. When we compare its output to equivalently decimated files ran through Python libs with a fifth order sinc filter, things look noisier. Almost like the decimater is doing an extra smoothing pass, beyond the documented sinc filter.
I've uploaded some comparisons: http://brainimaging.waisman.wisc.edu/~dfitch/biosemi/
For example, comparing inside BDFReader:
The "decimater" output:
Python output:
