How to make two seperate list of files from one list of files?

Hi all,

I have mutiple folders including 15 mat files (image below). The files are srtructures with mutiple tables inside.

I want to process in a loop files highlighted green using an operation and files highlighted red using a diffrent operation. The last three digits in the files name may differ depending on the folder.

I want to omit files that are not highlighted.

For this purpose, I want to make two seperate list of files and this is where I fail. Please help

%% List all files in the folder
all_files = dir(fullfile(Folder, '*.mat'));

%% List files highlighted green and red
green_files = all_files (2,3,7,8,12,13)
red_files = all_files (4,5,9,10,14,15)

Error: Index in position 2 exceeds array bounds (must not exceed 1).

%% Loop through each list of files
for k = 1:length(green_files)
  operation 1
end
for k = 1:length(red_files)
  operation 2
end

all_files = dir(fullfile(Folder, '*.mat'));
green_files = all_files([2,3,7,8,12,13])
red_files   = all_files([4,5,9,10,14,15])
