CONN toolbox troubleshooting: batch setup error

I'm following along Andy Jahns Brain Book- Chapter 12 Functional Connectivity Scripting.

My code runs well through "loading the files" scripted as.. ________________________

NSUBJECTS=6;

cwd=pwd;

FUNCTIONAL_FILE=cellstr(conn_dir('sub-*_func_sub-*_task-rest_bold.nii.gz'));

STRUCTURAL_FILE=cellstr(conn_dir('sub-*_anat_sub-*_T1w.nii'));

if rem(length(FUNCTIONAL_FILE),NSUBJECTS),error('mismatch number of functional files %n', length(FUNCTIONAL_FILE));end

if rem(length(STRUCTURAL_FILE),NSUBJECTS),error('mismatch number of anatomical files %n', length(FUNCTIONAL_FILE));end

nsessions=length(FUNCTIONAL_FILE)/NSUBJECTS;

FUNCTIONAL_FILE=reshape(FUNCTIONAL_FILE,[NSUBJECTS,nsessions]);

STRUCTURAL_FILE={STRUCTURAL_FILE{1:NSUBJECTS}};

disp([num2str(size(FUNCTIONAL_FILE,1)),' subjects']);

disp([num2str(size(FUNCTIONAL_FILE,2)),' sessions']);

TR=3.56; % Repetition time

___________________________________________________________

In my case, I have a return of 35 subjects and 1 session. Now I enter "the setup field" and get no return of my data. A .mat file should be created, and subsequent preprocessing steps should return outliers, among other output. The script runs through without error- but without any data produced. Any ideas?______________

%% CONN-SPECIFIC SECTION: RUNS PREPROCESSING/SETUP/DENOISING/ANALYSIS STEPS

%% Prepares batch structure

clear batch;

batch.filename=fullfile(cwd,'Arithmetic_Scripted.mat'); % New conn_*.mat experiment name

%% SETUP & PREPROCESSING step (using default values for most parameters, see help conn_batch to define non-default values)

% CONN Setup

% CONN Setup.preprocessing (realignment/coregistration/segmentation/normalization/smoothing)

(Preproccesing steps continue as consistent with Chapter #12 Scripting)___________________________
