Muscle artifact discussion: Computing threshold_muscle and the meaning of order?

💬 Support & Discussions

Hi @PaulF,

Is there a way to choose a reasonable threshold_muscle value using the zscore - Muscle Activity graph? For example, could I take the mean of the values on the graph plus one or two standard deviations?

This was answered in this discussion. The threshold is data-dependent, you have to check what value works in your case.

What do the values 144 and 164 in order represent?

These values are just channel indices that define which channels will be shown and in what order. So it is specific to the tutorial, better use all channels in your case (so you can leave this argument undefined).

What is the most efficient means to combine the starts and durations for the muscular artifacts and the starts and durations for the ocular artifacts so as to plot my raw data with both types of artifacts highlighted but in different colors?

If both are stored as annotations, you can add them together (annot1 + annot2) as far as I know.
