Hello, I just created a for loop and this is correct, but now I would only select positions from 30 to 48 for each "essai" but I am not sur how to do that whithout matrix size problem...
for essai = 1:length (nb_essai)
% for essai = 1:length (nb_essai)
num_ess = [];
num_ess = find (num(:,24) == essai);
Val_CursX_ess = num(num_ess,6);
Val_CursY_ess = num(num_ess,7);
Val_Quest_ess = txt(num_ess,36);
Val_Indice_ess = txt(num_ess,40);
Val_Valid_ess = txt(num_ess,33);

After
num_ess = find (num(:,24) == essai);
add
num_ess = num_ess(num_ess >= 30 & num_ess <= 48);

I try something like this but in final I lost information about my 'code_indice'. Is it possible just te redefine the size of matrix num,txt,raw before?
for essai = 1:length (nb_essai)
% for essai = 1:length (nb_essai)
num_ess = [];
num_ess = find (num(:,24) == essai);
%num_ess = num_ess(num_ess >= 30 & num_ess <= 48);
Val_CursX_ess = num(num_ess,6);
Val_CursY_ess = num(num_ess,7);
Val_Quest_ess = txt(num_ess,36);
Val_Indice_ess = txt(num_ess,40);
Val_Valid_ess = txt(num_ess,33);
% pause
%== boucle Question ==
for ques = 1:2
Question_interet = Type_Questions{ques};
[pos_question, index] = ismember ('Semantique', Val_Quest_ess);
%pos_question = find(strcmp(Question_interet,Val_Quest_ess) == 1);
Val_CursX_ess_Quest = Val_CursX_ess(pos_question,1);
Val_CursY_ess_Quest = Val_CursY_ess(pos_question,1);
Val_Quest_ess_Quest = Val_Quest_ess(pos_question,1);
Val_Indice_ess_Quest = Val_Indice_ess(pos_question,1);
Val_Valid_ess_Quest = Val_Valid_ess(pos_question,1);
if ques == 1
pos_ok = [];
[pos_ok, index] = ismember ('Emotion', Val_Quest_ess);
%pos_ok = find(strcmp('Semantique',Val_Indice_ess_Quest) == 0);
Val_Indice_ess_Quest = Val_Indice_ess_Quest(pos_ok,1);
Val_CursX_ess_Quest = Val_CursX_ess_Quest(pos_ok,1);
Val_CursY_ess_Quest = Val_CursY_ess_Quest(pos_ok,1);
Val_Quest_ess_Quest = Val_Quest_ess_Quest(pos_ok,1);
Val_Valid_ess_Quest = Val_Valid_ess_Quest(pos_ok,1);
% faut dégager les semantiques et conserver le reste
% --> créer un nouveau Val_Indice_ess_Quest
end
%-- Etat Indice -- Emo ou Neutre? --
% Code_Indice --> 1 pour Neutre
% Code_Indice --> 2 pour Emo
if strcmp(Val_Indice_ess_Quest(1,:),'Neutre')==1
code_Indice = 1;
elseif strcmp(Val_Indice_ess_Quest(1,:),'Emo')==1
code_Indice = 2;
else
code_Indice = 999;
end
if strcmp(Val_Valid_ess_Quest(1,:),'valide')==1
code_Vald = 1;
elseif strcmp(Val_Valid_ess_Quest(1,:),'invalide')==1
code_Vald = 2;
else
code_Vald = 999;
end

Maybe, it could be easier if I join the script and a file for run the script for my data
