Hi Conn Forum,

I'm a new user and am encountering an error when attempting to run a conn batch script. I have data that was preprocessed using the HCP pipelines and I would like to use the conn_batch_humanconnectomeproject.m script to import the data into conn. I have made the appropriate modifications to the script so that it finds my files (e.g., changed the names and number of resting state scans). 

When I run the script, my files are found and read correctly - but then I quickly get this error?

%%%%%%%%%%%%%%%%%%%%%%%%

Error using fprintf
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in conn_disp (line 162)
for n=1:numel(str), fprintf(fh,'%s\n',str{n}); end

Error in conn_process (line 27)
case 'setup_preprocessing', conn_disp(['CONN: RUNNING SETUP.PREPROCESSING STEP']); conn_setup_preproc(varargin{:});

Error in conn_batch (line 1099)
conn_process('setup_preprocessing',steps,'subjects',SUBJECTS,OPTIONS{:});

162 for n=1:numel(str), fprintf(fh,'%s\n',str{n}); end

%%%%%%%%%%%%%%%%%%%%%%%%

Using the real-time debugger in matlab, it appears that a file is attempting to be opened by fprintf. This file is taken from line 160-161 of the conn_disp.m:

%%%%%%%%%%%%%%%%%%%%%%%%

filename=fullfile(conn_prepend('',conn_projectmanager('projectfile'),''),'logfile.txt');
fh=fopen(filename,'at');

%%%%%%%%%%%%%%%%%%%%%%%%

It appears that conn is trying to open the log file, but this log file does not exist. I'm assuming that it should have been created in an earlier step that I may have neglected to complete. Any help that could be offered is appreciated!
