Hi there,

I'm building a GUIDE, where I use some popupmenus to chose some specs. like the day and some paths, and save them as .mat in a temporary folder.
In another popupmenu I use those like this:

 switch get(handles.VARIAVEL,'Value')
    
    case 2
        set(handles.STATUS,'String','Loadding Variable ...');
        
        load temp/dia.mat; %string
        dia
        load temp/lev.mat; %number
        load temp/path1.mat; %string
        load temp/path2.mat; %string
        
        out1 = netcdf([ path1 'wrfout_d03_2010-07-' num2str(dia) '_00_00_00']);       
        out2 = netcdf([ path1 'wrfout_d03_2010-07-' dia '_12_00_00']);  
..
..
..

But I'm never able to get the output of these commands.....
ERROR:

Is there any way of making it reconstruct the path and file to open?

Why don't you try using sprintf() to build up your base file name, and
then fullfile() to prepend the path to it?  And then use exist() to
check on its existence before you try to read it.
