Figure 3: Workflows of real-time data collection and processing using rtMEG (a) and of the optimal, off-line processing chain (b). For real-time data analysis, the forward head model and inverse imaging kernel were precomputed and applied online on all subsequent recordings. This differs from the optimal off-line pipeline, where forward and inverse modeling is completed for each individual run. In addition, interference suppression was performed in the client workstation using SSP on each data buffer during real-time data collection and analysis, whereas SSS was used over the entire duration of each individual run during the off-line analysis.
