SORM toolbox
SORM toolbox is a suite of MATLAB functions to design sensor arrays of Optically Pumped Magnetometers (OPMs). Based on the resolution matrix of Minimum Norm Estimate (MNE), it sequentially determines each sensor position so that the estimated cortical currents have accurate time-series at regions of interest (ROIs).
Applicability
SORM is useful when we want to accurately estimate ROIs' activities with a limited number of OPM sensors, such as brain-machine interfaces and diagnosing brain diseases.
