Option to view "2D Sensor Cap" doesn't render in the PSD file

vpkumaravel · June 23, 2021, 7:25pm

Hello all,

I wrote a custom process script to compute PSD. The output file contains the same kind of fields as one may find using the BSD's default Welch analysis. However, upon right-click on the PSD file, I do not see the option to view the 2D sensor cap (Ctrl + T).

Strange enough, using the same custom process file, everything works fine for a different EEG dataset with a different number of channels and sampling rate.

My question is - in the script, which parameter should I look for, to render the "right-click" options as done by the BST's Welch method.

Thanks in advance.

You probably need to check the filename as well.
You can also use the Matlab debugger on tree_callbacks.m to check step by step what menus are displayed in the popup, and why.

    dispMod = getChannelTypeDisplay(AllMod{iMod}, AllMod);

    jSubMenu = gui_component('Menu', jMenu, [], dispMod, IconLoader.ICON_TOPOGRAPHY, [], []);

    jSubMenus(iMod) = jSubMenu;

else

    jSubMenu = jMenu;

    jSubMenus = [];

end

if ~ismember(AllMod{iMod}, {'SEEG','ECOG+SEEG'})

    gui_component('MenuItem', jSubMenu, [], '3D Sensor cap', IconLoader.ICON_TOPOGRAPHY, [], @(h,ev)view_topography(FileName, AllMod{iMod}, '3DSensorCap', [], UseSmoothing, hFig));

    if ~ismember(AllMod{iMod}, {'NIRS','ECOG'})

        gui_component('MenuItem', jSubMenu, [], '2D Sensor cap', IconLoader.ICON_TOPOGRAPHY, [], @(h,ev)view_topography(FileName, AllMod{iMod}, '2DSensorCap', [], UseSmoothing, hFig));

        gui_component('MenuItem', jSubMenu, [], '2D Disc',       IconLoader.ICON_TOPOGRAPHY, [], @(h,ev)view_topography(FileName, AllMod{iMod}, '2DDisc',      [], UseSmoothing, hFig));

    end

end

% 2D Layout

if is2DLayout

    gui_component('MenuItem', jSubMenu, [], '2D Layout', IconLoader.ICON_2DLAYOUT, [], @(h,ev)view_topography(FileName, AllMod{iMod}, '2DLayout'));

end

% 3D Electrodes

if ~AlwaysCreate

    if strcmpi(AllMod{iMod}, 'EEG')

Hello @Francois, Thanks for your help, I was able to figure out the bug in a short period of time. It was also a learning experience. Apparently, the issue was with assigning the channel names due to which the variable "AllMod" was empty! Have a good day!
