Description

Dear MNE team,
I'm using corrmap() for independent components analysis, is it possible to use more than one component as template? For exemple selecting blinks and ecg components as the same time?

For exemple:

subj_number = [0]
component_numbers = [1, 3]
template_components = icas[subj_number].get_components()[component_numbers]
fig_template, fig_detected = corrmap(icas, template=template_components, threshold=0.9, label='artifacts', ch_type='eeg')

But I get an error when doing this, corrmap seems not to support template larger than (subject_index, component_index) is there another way to do it?

Thanks

Research direction

Start at the corrmap entry point and inspect how its template argument is validated and used, along with any existing corrmap tests. Determine the expected behavior for multiple independent components, including separate blink and ECG templates, then add coverage that defines successful handling and its result.
