I am writing a code that replaces values around an EEG data file where there is a 9, it changes the values (4 to the left and 7 to the right) to 5:16 for option 2 and for option 3, it would look for number 59 and replaces values around it from 58 to 63.
function OUTEEG = FormatEEGarry(EEG,option)
x= pop_loadset;
optionChoose = inputdlg('What option do you want?:', 'Option input',[1,30])
option = str2num(optionChoose{:}); %option chosen and stored
search_9 = find([x.event.epochtype]==9);
search_59 = find([x.event.epochtype]==59);
if option ==1
for k=1:size(x.event,2)
temp= x.event(k).epochtype
if [x.event(k).epochtype] ~=1;
x.event(k).epochtype =99;
end
disp([temp x.event(k).epochtype])
end
end
if option ==2
for ii= 1:size(search_9);
temp= x.event(ii).epochtype;
if (search_9(ii)+7) <= size([x.event.epochtype],2)
if (search_9(ii)-4) >= 1
ringa = search_9(ii) + [-4:7];
[x.event(ringa).epochtype]= 5:16;
end
end
disp([temp x.event(ii).epochtype])
end
end
i keep getting an error for the line
[x.event(ringa).epochtype]= 5:16;
and the error is Undefined function or variable 'ringa'.
Error using subsindex Function 'subsindex' is not defined for values of class 'struct'.
An alternative choice for option 2 that i used is as follows,
if option ==2
temp = x.event(ii).epochtype
Z = +regexprep(char(x.event.epochtype),sprintf('.{0,4}%c. {0,7}',9),char(5:16))
disp([temp x.event(k).epochtype])
end
This seems to do half the job and changes the data around 9 to 1 1 1 9 10 11 12 1 1 1. Which is not quite there yet.
I am not really sure what to do here??

Time to use the debugger
dbstop if error
then run the code. When it stops with the error about ringa not being defined, verify that the line before is indeed
ringa = search_9(ii) + [-4:7]
and make sure that the spelling of the variable is exactly the same. Point to the variable in the line before to see its value. Use "whos" to see which variables are in the workspace.
