Also the variables ID, k and limiar are supposed to be inputs , for rigth now I'm just having them as fixed values since is easier to try and find the problem that way
The code works but the values don't match and I can't find the error

The code is the following and its objective is to obtain the coordenates of peaks od the signal FINAL whose graphic is attached.
However the values don't match and I can't find the problem .
Can someone help?
clear
clc
ID = 1;
sinal = read_ecg_txt (ID);
filtrado = remove_noise(sinal,101);
FINAL = Remove_noise2(filtrado,20);
k = 500;
limiar = 300;
L = length(FINAL);
Picos = [];
a = (k-1)/2;
t = 1;
for i = 1:k:L
if i<(ceil(a))
for q = 1:k
maximo = 0;
if FINAL(q) > maximo
maximo = FINAL(q);
M = q;
end
end
Picos(t,1) = maximo;
Picos(t,2) = M;
t = t + 1;
elseif i>(L-(floor(a)))
for q = (L - k):L
maximo = 0;
if FINAL(q) > maximo
maximo = FINAL(q);
M = q;
end
end
Picos(t,1) = maximo;
Picos(t,2) = M;
t = t + 1;
else
for q = (i-(ceil(a))):(i + (floor(a)))
maximo = 0;
if FINAL(q) > maximo
maximo = FINAL(q);
M = q;
end
end
Picos(t,1) = maximo;
Picos(t,2) = M;
t = t + 1;
end
end
m = 1;
Peaks = [];
for p = 1:(t-1)
if Picos(p,1) > limiar
Peaks(m,1) = Picos(p,1);
Peaks(m,2) = Picos(p,2);
m = m + 1;
end
end

read_ecg_txt() remove_noise() Remove_noise2() are missing
for q = 1:k
maximo = 0;
if FINAL(q) > maximo
maximo = FINAL(q);
M = q;
end
Resetting maximo = 0 each iteration of the loop is suspicious.
Consider using
[maximo, M] = max(FINAL(1:k));
with no loop.
