Matlab image features extraction error (ifcb-analysis)

I am trying to use that code included in the file "start_blob_batch_user_training.m" in the ifcb-analysis set (https://github.com/hsosik/ifcb-analysis).

function [ ] = start_blob_batch_user_training(in_dir_base , out_dir_blob_base, parallel_proc_flag)
%function [ ] = start_blob_batch_user_training(in_dir_base , out_dir_blob_base, parallel_proc_flag)
%For example:  
%start_blob_batch_user_training('C:\work\IFCB\user_training_test_data\data\2014\', 'C:\work\IFCB\user_training_test_data\blobs\2014\', false)
%IFCB image processing: configure and initiate batch processing for blob extraction
%Heidi M. Sosik, Woods Hole Oceanographic Institution, Aug 2015

%example input variables
%   in_dir_base = 'C:\work\IFCB\user_training_test_data\data\2014\'; %USER local data location (where are your *.roi files)
%   out_dir_blob_base = 'C:\work\IFCB\user_training_test_data\blobs\2014\'; %USER local data location for blob reults
%   parallel_proc_flag = false; %USER true to enable parallel processing

if ~exist('parallel_proc_flag', 'var')
    parallel_proc_flag = false; %default
end

if ~exist(out_dir_blob_base, 'dir'),
    mkdir(out_dir_blob_base)
end;
daydir = dir([in_dir_base 'D*']);
%daydir = dir([in_dir_base 'IFCB1_2015_160*']);
daydir = daydir([daydir.isdir]); 
bins = [];
in_dir = [];
out_dir_blob = [];
for ii = 1:length(daydir)
    in_dir_temp = [in_dir_base daydir(ii).name filesep];
    bins_temp = dir([in_dir_temp '*.adc']);
        if ~isempty(bins_temp)
    bins_temp = regexprep({bins_temp.name}', '.adc', '');
    daystr = char(bins_temp(1)); daystr = daystr(1:9);
%%TEMP FOR OLD MVCO STYLE v2
   % daystr = char(bins_temp(1)); daystr = daystr(2:9);
   %    daystr = char(bins_temp(1)); daystr = daystr(7:14);
    out_dir_blob_temp = [out_dir_blob_base daystr filesep];
    bins_done = dir([out_dir_blob_temp '*.zip']);
    bins_done = regexprep({bins_done.name}', '_blobs_v2.zip', '');
    [bins_temp,ia] = setdiff(bins_temp, bins_done);
end
    if ~isempty(bins_temp)
       daystr = char(bins_temp); daystr = daystr(:,1:9);
   %      daystr = char(bins_temp); daystr = daystr(:,1:14);
        in_dir = [in_dir; repmat(cellstr(in_dir_temp),length(bins_temp),1)];
        out_dir_blob_temp = cellstr([repmat(out_dir_blob_temp,length(bins_temp),1)]);
        out_dir_blob = [out_dir_blob; out_dir_blob_temp];
        bins = [bins; bins_temp];
    end;
end;

nfiles = length(bins); 
disp(['processing ' num2str(nfiles) ' files'])
if nfiles > 0
    batch_blobs(in_dir, out_dir_blob, bins, parallel_proc_flag);
end

end

I first referenced the path of the input directory and the output directory (macos) :

in_dir_base = '/Users/user/Documents/user_training_test_data/data/2014/';
out_dir_blob_base = '/Users/user/Documents/user_training_test_data/blobs/2014/';

But when I launch the code I receive that error :

"Not enough input arguments.

Error in start_blob_batch_user_training (line 17)

if ~exist(out_dir_blob_base, 'dir'),"

How could this be fixed?

For the dataset, I used the "Test data" provided the in the instructions of the ifcb-analysis set (https://github.com/hsosik/ifcb-analysis/wiki/Blob-extraction,-feature-extraction,-and-classifier-application#instructions-for-blob-extraction)

Unfortunately, *.roi files are too voluminous to be added as a reproductible example here...

After some test I realised the problem came from the fact the function needed to be launched from another matlab file. Of course, the other file need to define the variables in_dir_base , out_dir_blob_base, parallel_proc_flag and after launch the function.

The code in the new file is then the following :

in_dir_base = 'Path/to/data/';
out_dir_blob_base = 'Path/to/output/';
parallel_proc_flag = false;
start_blob_batch_user_training(in_dir_base , out_dir_blob_base, parallel_proc_flag)

Launching the code from the newly created Matlab instead of inside the "start_blob_batch_user_training.m" fix the error.
