Hi everyone,

I am new to CONN and currently trying to preprocess my data. I want to do functional segmentation since I did not acquire a structural/T1 image for my participants.
I followed the steps described in a previously asked question in this forum: "Preprocessing without structural/T1 image".
I chose the default MNI pipeline, removed the structurals_* steps and added the functional_segmentation step after normalization and before smoothing.
Preprocessing runs normally until the segmentation step, although this step seems to run without any errors as well, since it says "Done 'Segment'". Nevertheless,
when CONN wants to update the CONN_* structure, the following error occurs:

-------------------------------------------------------------------------------------------------------
Cell contents reference from a non-cell array object.

Error in conn_setup_preproc (line 1256)
CONN_x.Setup.rois.files{nsubject}{1}{nses}=conn_file(outputfiles{isubject}{min(nses,nsesstemp)}{2});
Error in conn (line 717)
ok=conn_setup_preproc('',varargin{2:end});
Error in conn_menumanager (line 119)
feval(CONN_MM.MENU{n0}.callback{n1}{1},CONN_MM.MENU{n0}.callback{n1}{2:end});
CONN v.15.f
SPM12 + DEM FieldMap MEEGtools
Matlab v.2013a

Do you have any idea where this error might come from?
Thanks a lot for your help!
Cheers, Nils
