How to downsample the src points?

Hi,

I morph the stc results to fsaverage, to make each subjects have the same source points.

test_stc = mne.read_source_estimate(save_name)
stc_fs = mne.compute_source_morph(
test_stc, ‘S’ + sub, “fsaverage”, subjects_dir, smooth=5, verbose=“error”
).apply(test_stc)

However, for “stc_fs”, there are 20484 points and it is too much for my anaylsis. How can i downsample to less points,eg 5k or 10k?
