Important notes
- Distribution:
- In all the tutorials, we will consider that you are working with the source distribution of Brainstorm.
- If you are running a stand-alone distribution: some menus might be missing, some indications might not applicable to you, but everything else should work the same way.
- Before starting using Brainstorm with your own data:
You should go through all the tutorials in the following section: "Getting started with Brainstorm". In just a few hours, they will introduce you to most of the main features of the application.
- Then you can read more specific tutorials, closer to your personal interests.
- If you want a printed version of this documentation:
- Open a tutorial, go to the menu on top of the page,
Select More actions > Print view, print the page, and go to the next tutorial.
Getting started with Brainstorm
Dataset description
The dataset that will be used for tutorials #2 to #10 is a somatotopy experiment recorded with a CTF 151 MEG system.
Please download bst_sample_ctf.zip from the Download section. Unzip it in a folder you will dedicate to original data. It can be anywhere but not in the Brainstorm database or program folder. Example:
Windows: My documents\MEG\sample_ctf\
Linux: /home/username/MEG/sample_ctf/
MacOS: Documents/MEG/sample_ctf/
File: |
bst_sample_ctf.zip |
Acquisition system: |
CTF MEG, 151 axial gradiometers, La Salpetriere Hospital, Paris |
Protocol: |
Shuffled electrical stimulations of the thumb fingers from both hands. The idea is to get a map of the primary sensory response on the cortex |
Author: |
Data provided courtesy of Sabine Meunier |
Anatomy directory: |
- T1-MRI of the subject in CTF format (.mri). |
Datasets directory: |
- somMGYO-18av.ds: average response for the stimulation of the right thumb (one subject, 400 trials) . |
Observations: |
Stimulus occurs at time 0. There's a first tiny wave occuring at about 20ms or so but it's not too clear on all fingers. So if you are to compute cortical maps, start by the 40ms peak which is also of interest and which has much better SNR. |
