mne_add_triggers

Overview

mne_add_triggers adds trigger events to a raw data file's stimulus (STI) channel. It reads a trigger file with sample–value pairs and writes the events into the STI channel of the raw data. The tool prefers STI 014 but falls back to the first available stimulus channel.

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

Usage
