MATLAB: How to link two radiobutton groups

matlab gui

Best Answer

Don't use the tag property for the ages. Use the Value property to get the index. The check for cases 1, 2, 3, 4, etc. (integers, not strings).

Also you mgiht have to convert calorie to a string to put it into the String property:

set(handles.text2, 'String', num2str(calorie));

Mohmd - you have two push button callbacks as follows

 function pushbutton1_Callback(hObject, eventdata, handles)
 humanHEXA = getgenbank('NM_000520')
 humanProtein = nt2aa(humanHEXA.Sequence,'frame',3)
 function pushbutton2_Callback(hObject, eventdata, handles)
 mouseHEXA = getgenbank('AK080777')
 mouseProtein = nt2aa(mouseHEXA.Sequence)

where each defines local variables humanProtein and mouseProtein respectively. Your checkbox callbox is defined as

 function checkbox2_Callback(hObject, eventdata, handles)
 seqdotplot(mouseProtein,humanProtein,4,3)
 ylabel('Mouse hexosaminidase A (alpha subunit)')
 xlabel('Human hexosaminidase A (alpha subunit)')

The first line of code (after the signature) references two undefined variables, the mouseProtein and humnaProtein. This is probably the source of your error: your code is referencing variables that have been defined locally in other callbacks. When using GUIDE to design your GUI, if you create a local variable in one callback function that you want to reference in another callback function, you need to save this variables as user-defined data within the handles structure. To do this, change your pushbutton callbacks as follows

 function pushbutton1_Callback(hObject, eventdata, handles)
 humanHEXA = getgenbank('NM_000520');
 handles.humanProtein = nt2aa(humanHEXA.Sequence,'frame',3);
 guidata(hObject,handles);
 function pushbutton2_Callback(hObject, eventdata, handles)
 mouseHEXA = getgenbank('AK080777');
 handles.mouseProtein = nt2aa(mouseHEXA.Sequence);
 guidata(hObject,handles);

In the above, we save each local variables as a field within handles and then save the updated structure using guidata. Now, in your checkbox callback, you would do

 function checkbox2_Callback(hObject, eventdata, handles)
 if isfield(handles,'mouseProtein') && isfield(handles,'humanProtein')
     seqdotplot(handles.mouseProtein,handles.humanProtein,4,3);
     ylabel('Mouse hexosaminidase A (alpha subunit)');
     xlabel('Human hexosaminidase A (alpha subunit)');
 end

In the above, we check to see if the handles structure has the two fields that we are interested in using isfield. If both exist, then we get each variable by accessing the desired field within that structure.

Try the above and see what happens!

MATLAB: Setting up a nested data structure

Your information architecture diagram doesn't look quite right. For example, your [Females] should be a structure that holds heights and times, but you have it as an array of heights. I think you want something like this:

female_times = struct('Manual',manual_time,'Matlab',matlab_female);
Female = struct('Heights',female,'Times',female_times);
% ditto for males to make struct Male
SortedHeights=struct('Female',Female,'Male',Male)

FWIW, I would question using an information architecture like this in the first place. Why not, for example, just keep the times in a 2x2 array (gender, manual/matlab)?
