Correlation graph

When I try to display the correlation analysis between scouts on EEG data as a graph in Brainstorm, the graph does not load, although the corresponding image loads normally. Some correlation analyses I performed previously load correctly both as images and graphs.
What can be the issue?

  • Is there any error message in the Matlab command window?
  • "the graph does not load". Is the entire figure missing or the links in the graph?

Yes I have this error :

Error in view_connect (line 275)
figure_connect('LoadFigurePlot', hFig);

Error in tree_callbacks>@(h,ev)view_connect(filenameRelative,'GraphFull') (line 2033)
                            gui_component('MenuItem', jPopup, [], 'Display as graph [NxN]',   IconLoader.ICON_CONNECTN, [], @(h,ev)view_connect(filenameRelative, 'GraphFull'));

The error message seems incomplete.
Could you share one of the connectivity files that is giving you the error?
