A guide for running standard analysis steps at the center.


Starting guide

Data at the CENIR is stored on the ICM network. Below are guides to find and work on your data as needed.

Each of the three main external toolboxes used at the MEEG center have their own environment and way of thinking about the data. We strongly advice you to choose wisely once and for good for a given project.

See this page for guidance: Choose your toolbox

The document below provides a complete processing pipeline with in depth description (using the MNE toolbox).


Data acquisition and preprocessing

Specifics of data acquisition, modalities and hardware at the MEEG center require your attention.

Data acquisition and fusion

At the MEEG center, you can acquire data in various modalities (MEG, EEG, eye tracking, fNIRS, MRI...). Each of these has its own specifics (file format, sampling frequency, number of channels, coordinate system...). We have in-house tools to merge data from different modalities within a consistent framework accepted by all external toolboxes.

  • Anatomical data should be acquired at the center following the specifications on this sheet Fiche_protocole_generique_Anat_MEG_Prisma_Verio_v0.pdf
  • If you use MEG, all data is converted from vendor-specific file formats to the widely used .fif file format, originally implemented by Elekta, our MEG vendor.

Preparation

Cleaning

Time-locked data analysis

Epoched data uses segments of data recorded during repeated occurrences of an event.

Continuous data analysis

Continuous data uses unsegmented streaks of data recorded during (usually) long periods without specific events.

  • Resting state
  • Epilepsy

Experimental techniques

Tests and evaluation of new experimental approaches.

Statistical analysis

Statistical tests are closely related to the experimental design
