dmri_plot_dmri_connections_matrix

 Plot dmri connection between regions.
 [Usage]
    h = dmri_plot_dmri_connections_matrix(dmri_file, brain_file, area_file);

 [Input]
    dmrifile  : connectivity matrix obtained from DMRI processor
    brainfile : brainfile of VBMEG
    areafile  : areafile of VBMEG. coarse region parcellation such as AAL and
                brodmann. AAL is recommended.

 [Output]
    h : figure handle
