if Sign == 1
if appm==0
x{end+1,1}.AppName=aa1{selA,1}.Type;
status='[On]';
dataOn=i-7;
app=AppName;
appm=1;
end
SignStr = '[On]';
iCount = iCount + 1;
if ~isempty(r{selA,1})
r{selA,1} = r{selA,1} + 1;
else
r{selA,1} = 1;
end
else
if x{end}.AppName == aa1{selA,1}.Type
AppName=aa1{selA,1}.Type;
status='[Off]';
dataOff=i-7;
end

It likely visible that you have a fieldname AppName from the if statement but then in the next step you assign AppName as if it is defined to app perhaps you are meant to assign with dot indexing like you did in if statement with struct x{...}.AppName

It's clearly a variable but you're treating it as a struct change your lines to below:
dataOn(end-1) and the next dataOn(end)

but ; Reference to non-existent field 'dataOn'.
Error in MainTest (line 767)
xx{end+1,1}.number=x{end}.dataOn-d{end-1}.dataOn;
