Hello all,

I want to find the threshold for various trials, contained in the structure "Target_Tr.". I have previously calculated the max value (X and Y) of the baseline. I would like to have as result a structure array containing the values after the threshold. I wrote this code, but the system gives me back the error message "Undefined operator '>' for input arguments of type 'struct'. What am I doing wrong?

Thank you very much

clear a
for a = 1:length(fields_trials)
Threshold_Target_X.(['a_' int2str(a)])=find([Target_Tr.(fields_trials{a})]>Target_Max_Y);
end

Hi,

Without knowing what your data looks like, it's hard to answer.

I tried this code and it works :

Target_Tr.s1 = rand(10,1);
Target_Tr.s2 = rand(10,1);
fields_trials = fieldnames(Target_Tr);
Target_Max_Y = 0.6;
clear a
for a = 1:length(fields_trials)
    Threshold_Target_X.(['a_' int2str(a)]) = find([Target_Tr.(fields_trials{a})]>Target_Max_Y);
end
