NatMEG wiki


This wiki page is intended for NatMEG researchers, alongside the NatMEG website. It contains information of internal procedures such as MEG recordings, data archiving and (in the near future) information about analysis. Content on this page is under (rapid) development, and indeed is intended to continuously remain so. Contributions from the (Nat)MEG community are highly appreciated and we hope this site will become a platform for exchange of knowledge about MEG recording and analysis. If you would like to contribute, please email us to receive an account.

Please feel free to use anything, but not without mentioning due credit.
