NIRSTORM: a Brainstorm plugin specialized in the analysis of fNIRS data
Author: Édouard Delaire, Lea Larreur, Dr. Zhengchen Cai, Dr. Christophe Grova
This tutorial aims to introduce NIRSTORM. NISTORM is a plug-in dedicated to the analysis of functional near-infrared spectroscopy (fNIRS) data inside Brainstorm.
This tutorial will cover three main aspects of NIRSTORM:
- Data importation and preprocessing
- Data analysis at the channel level
- Data analysis on the cortical surface.
This tutorial assumes that you are already familiar with the Brainstorm environment. If you are not, we encourage you to follow the tutorial 1 to 23.

Introduction
Presentation of the experiment
The data presented in this tutorial correspond to a finger tapping task perform by one subject using their left, non-dominant hand. NIRS montage was done to target the subject right-motor cortex.
Data description:
• One subject, one run of 19 minutes acquired with a sampling rate of 10Hz on a CW fNIRS Brainsight device (Rogue-Research Inc., Montreal, Canada)
• Finger tapping task: 20 blocks of 10 seconds each, with a rest period of 30 to 60 seconds.
• 3 sources, 15 detectors, and 1 proximity detector.
• 2 wavelengths: 685nm and 830nm
• 3T MRI anatomy processed by FreeSurfer 5.3.0.
Setup
You can install the mtrf manually from Brainstorm directly. For that, go to Plug-ins > fNIRS > nirstorm.
