GRETNA_modularity

Dear Dr. Yan,

I used the 90*90 FC matrix to calculate the topological metric-Modularity on the GRETNA. Several results can be obtained , but I dont kown their meaning: "community_index_All_Node", "participant_coefficient_All_Node", and "size_of_maximum_component". The author of GRETNA did not explain the meaning of these measurments in the Mannual. Could you help me? 

Thanks very much!
