= Introduction =
Brainstorm is a free Matlab application dedicated to Magnetoencephalography(MEG) and Electroencephalography(EEG) data visualization, processing and cortical source estimation. <
>Our intention is to make a comprehensive set of tools available to the scientific community involved in MEG/EEG experimental research.<
>For physicians and researchers, the interest of this software package resides in its rich and intuitive graphic interface, which does not require any programming knowledge.
== What you can do with Brainstorm ==
* Import MEG / EEG recordings from the most popular file formats ([[FileFormats|list here]])
* Pre-processing:
* Epoching
* Averaging
* Frequency filtering
* Resampling
* Noise covariance estimation
* Manual definition of bad channels and bad epochs
* Data visualization:
* Various time series displays
* Data mapping on flat surfaces or the head envelope
* Generate slides and animations
* Channel selection, and manipulation of clusters of electrodes
* 3D surface rendering
* MRI visualization and coregistration:
* Analysis on individual anatomy or MNI / Colin27 brain.
* Import MRI scans, from most of the existing file formats ([[FileFormats|list here]])
* Co-registration with the MEG/EEG coordinate system
* Volume rendering (several display modes)
* Deformation of the MNI template to fit an set of digitized head points
* Database:
* Classification of recordings with three levels of definition (protocol, subject, condition/event)
* Quick access to all the data in a study
* Quick comparison between subjects or conditions
* Graphical batching tools (apply a same process to many files in a few clicks)
* Forward modeling:
* Single sphere method
* Overlapping spheres method
* Inverse modeling:
* Minimum-norm imaging of the cortical current density
* dSPM
* sLORETA
* Source display and analysis:
* Surface rendering of the estimated sources
* Reprojection of the sources in the MRI volume
* Definition of cortical regions of interest (scouts)
* Reprojection of estimated sources on a surface with a higher or lower definition
* Group analysis:
* Registration of individual brains on the MNI "Colin27" brain
* Statistical analysis (t-tests, permutations)
* Documentation and support:
* Easy and automatic updates of the software
* Detailed step by step tutorials for most of the common features
* Active user forum
== What you cannot do with Brainstorm ==
* Intensive pre-processing of MEG/EEG recordings (noise cancelling, artifact correction/rejection, etc.):<
> => use your constructor's software, or other software solutions (MNE, EEGLab, FieldTrip, etc.). [[Links|See here]].
* MRI segmentation:<
> => use !FreeSurfer, !BrainSuite or !BrainVisa. [[Links|See here]].
