    Metadata details:
    filename: mne_get_current_comp.m
    path of file: ./repos/fieldtrip/external/mne
    
    the code of the file until where you have to start completion: function [comp] = mne_get_current_comp(info)
%
% [comp] = mne_get_current_comp(info)

    
function [comp] = mne_get_current_comp(info)
%
% [comp] = mne_get_current_comp(info)
