how to analyze the weight amplitude of each channel sorted by its importance？ about mvpalab HOT 4 CLOSED

Dear Bo Sun,

In order to extract the associated weight to each channel you should select the "Weight vector" as an output in the study configuration window (this checkbox is located in the Classification model tab). Once the analysis is computed and completed you can plot the weight vector as follows:

• Open the "Plot result utility".
• Click on "Weight analysis" tab.
• Select the result file containing the weights vector time series (it should be located on result/time_resolved/wvector/haufe_corrected/result.mat).
• Configure the resulting plot or animation (start and end time, subject to plot, animation or temporal average, etc.)
• Click on "Plot" button.

Please let me know if this solves your problem.

Best,
