Here is my current folder/subfolder set up

Study > Participant (1-24) > Experiment (A) and Experiment (B) > Session (1, 2, and 3)

Folder that contains all participants data for this study
Subfolder participants folder (1-24)
Subfolder with data from experiment A and a subfolder for experiment B
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:

Loops through each participants subfolder
Runs Script 1 in the Experiment A subfolder for each session
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
