Hi, Im trying to run the Demo_script in my mac and this error keeps popping up. Unrecognized function or variable 'graph_conn_comp_mex'. Error in graph_connected_comp (line 26) [l c] = graph_conn_comp_mex(sA); Error in merge_components (line 65) [l,c] = graph_connected_comp(sparse(FF3+FF3')); % extract connected components Error in demo_script_AC (line 98) [Am,Cm,K_m,merged_ROIs,Pm,Sm] = merge_components(Yr,A_keep,b,C_keep,f,P,S,options); I've tried a couple of things but nothing seems to fix it. Any ideas how to troubleshoot?
