| Line 20: | Line 10: |
| * 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 * Graphic batching tools (apply a same process to many files in a few clicks) |
Our objective is to share a comprehensive set of user-friendly tools with the scientific community using MEG/EEG as an experimental technique. For physicians and researchers, the main advantage of Brainstorm is its rich and intuitive graphic interface, which does not require any programming knowledge. We are also putting the emphasis on practical aspects of data analysis (e.g., with scripting for batch analysis and intuitive design of analysis pipelines) to promote reproducibility and productivity in MEG/EEG research. Finally, although Brainstorm is developed with Matlab (and Java), it does not require users to own a Matlab license: an executable, platform-independent''' ''' (Windows, MacOS, Linux) version is made available in the [[Download|downloadable package]]. |
| Line 26: | Line 12: |
| * Forward modeling: * Single sphere method * Overlapping spheres method * Realistic head models using BEM and FEM * Inverse modeling: * Minimum-norm imaging of the cortical current density |
Since the project started by the end of the 1990's, our server has registered more than 6,000 software downloads and about 500 users are actively updating the software. See our [[Pub|reference page]] for a list of published studies featuring Brainstorm at work! |
| Line 33: | Line 14: |
| * Group analysis: * Registration of individual brains on the MNI "Colin27" brain * Statistical analysis (t-tests, permutations) |
The best way to learn how to use Brainstorm, like any other academic software, is to benefit from local experts. However, you may be the first one in your institution to consider using Brainstorm for your research. We are happy to provide comprehensive [[http://neuroimage.usc.edu/brainstorm/Tutorials|online documentation]] and support through[[http://neuroimage.usc.edu/forums|our forum]] but there is nothing better than a [[Training|course]] to make your learning curve steeper. Consult our [[Training|training pages]] for upcoming''' '''opportunities to learn better and faster! |
