Best way to loop through multiple subfolders and run either script A or B depending on folder name?

Here is my current folder/subfolder set up
Study > Participant (1-24) > Experiment (A) and Experiment (B) > Session (1, 2, and 3)
  1. Folder that contains all participants data for this study
  2. Subfolder participants folder (1-24)
  3. Subfolder with data from experiment A and a subfolder for experiment B
  4. Subfolder for session 1, 2, and 3
I have a code that works at the last level - I can analyze 1 session at a time with a script designed for Experiment 1, and another script that analyzes 1 session for Experiment 2.
However this would be very time consuming to analyze each session 1 at a time.
Therefore, my I am trying to figure out how to make a loop that does the following:
  1. Loops through each participants subfolder
  2. Runs Script 1 in the Experiment A subfolder for each session
  3. Runs Script 2 in the Experiment B subfolder for each session
It's important that Script 1 does not run for Experiment B and vice versa because the data, variable names, etc are different.
Hopefully this, appreciate any help that can be offered

If you have adopted a logical naming system for the files and directories, something simple like this would do:
for P = 1:24 % loop over participants
Pstr = sprintf('Participant%d',P) ;
for S = 1:3 % loop over sessions
Sstr = sprintf('Session%d', S) ;
fileA = fullfile('Study', Pstr, 'ExpA', Sstr, 'data.mat')
ResultsA (P,S) = MyAnalysisA(fileA) ; % if a single element is returned
% and something similar for B
end
end

path = 'Whatever path your study folder lies in';
folders = split(genpath(path), ';');
matchExpA = cellfun(@any, regexpi(folders, '.*\\experiment \(a\)\\session.*'));
matchExpB = cellfun(@any, regexpi(folders, '.*\\experiment \(b\)\\session.*'));
% analyze experiment A
for sessionCell = folders(matchExpA)'
session = sessionCell{1}; % get the folder path of current session in experiment A
% run script for analyzing experiment A
end
% analyze experiment B
for sessionCell = folders(matchExpB)'
session = sessionCell{1}; % get the folder path of current session in experiment B
% run script for analyzing experiment B
end
If you are working on a linux system those regular expressions probably need a small change but thats the general idea
