Need help with looping data files in

Hi, I've been working on writing this script that's supposed to read in 24 files, in sets of 3 as there are 3 trials being ran for different weight amounts. My issue is that it's only keeping the last 3 files worth of data while overwritting the rest. I know its due to how I set up my for loops I'm just unsure of how to fix it, as I've been looking around and trying different things without any luck.

HeaderRowCount = 7;
trials = 3;

for idx = setdiff(0:10:150,[30:10:40 60:10:90 130:10:140])
    for R = 1:trials
        A = importdata(['Static_' num2str(idx) 'g_5in_T' num2str(R) '.txt'], '\t', HeaderRowCount);
        Strain{R} = A.data(1:end-1,2);
        M(R) = mean(A.data(1:end-2,2));
        
    end
end

Here's my code for reference. The reason I have that array in the setdiff is due to my weights being 0,10,20,50,100,110,120,150. Any help would be great, thanks.

HeaderRowCount = 7;
trials = 3;

idx = setdiff(0:10:150,[30:10:40 60:10:90 130:10:140]);

for i = 1:length(idx)
    for R = 1:trials
        A = importdata(['Static_' num2str(idx(i)) 'g_5in_T' num2str(R) '.txt'], '\t', HeaderRowCount);
        Strain{i,R} = A.data(1:end-1,2);
        M(i,R) = mean(A.data(1:end-2,2));
        
    end
end

Alternatively, you could write the index as such:

idx = [0,10,20,50,100,110,120,150]

Hi, so I just figured it out. I changed it to this

clc;
clear;
close all;

HeaderRowCount = 7;
trials = 3;
i = 0;
for idx = [0,10,20,50,100,110,120,150]
    i = i + 1;
    for R = 1:trials
        A = importdata(['Static_' num2str(idx) 'g_5in_T' num2str(R) '.txt'], '\t', HeaderRowCount);
        Strain{i,R} = A.data(1:end-1,2);
        M(i,R) = mean(A.data(1:end-2,2));
        
    end
end

I'm getting an 8x3 maxtrix which is great, thanks for the help.
