mne_make_derivations

Overview

mne_make_derivations parses a text channel derivation file and writes it as a FIFF named matrix. Channel derivations define how derived (virtual) channels are computed as linear combinations of physical channels.

This is a C++ port of the original MNE-C tool by Matti Hämäläinen.

Usage

mne_make_derivations [options]

Options

Option	Description
--in <file>	Input text derivation file
--out <file>	Output FIFF file
--help	Print help
--version	Print version

Derivation File Format

One derivation per line with the following format:

derived_name = coeff1 * ch_name1 + coeff2 * ch_name2 + ...

Example:

EOG_bipolar = 1.0 * EOG061 + -1.0 * EOG062
ECG_bipolar = 1.0 * ECG063 + -1.0 * ECG064

Example

mne_make_derivations --in derivations.txt --out derivations.fif
