MEGSIM single trial simulation datasetΒΆ

The MEGSIM consists of experimental and simulated MEG data which can be useful for reproducing research results.

The MEGSIM files will be dowloaded automatically.

The datasets are documented in: Aine CJ, Sanfratello L, Ranken D, Best E, MacArthur JA, Wallace T, Gilliam K, Donahue CH, Montano R, Bryant JE, Scott A, Stephen JM (2012) MEG-SIM: A Web Portal for Testing MEG Analysis Methods using Realistic Simulated and Empirical Data.
