Error message - Reference to non-existent field 'X1'.
Hi,

This is the first time I am using CONN for the rsfMRI data analyses. My target is to generate a functional connectivity matrix containing correlation value between ROI-to-ROI.

My rsfMRI image volumes, anatomical image, as well as the atlas were co-registered using SPM and then I used these preprocessed data for SBC analyses. Just to check the pipeline working properly, I included only one subject and executed 1st-level SBC analyses. There were in total 80 brain regions coregistered into rsfMRI space. But when I select any region for ROI-to-ROI analyses (from 1st-level analyses tab), I get the following error message:

ERROR DESCRIPTION:

Reference to non-existent field 'X1'.
Error in conn (line 7347)
[CONN_h.menus.m_analyses.X,CONN_h.menus.m_analyses.select,names]=conn_designmatrix(CONN_x.Analyses(ianalysis).regressors,CONN_h.menus.m_analyses.X1,[],{nregressors,nview});
CONN20.b
SPM12 + DAiSS DEM FieldMap MEEGtools
Matlab v.2019b
project: CONN20.b
storage: 549.9Gb available

Could you please guide me how to resolve this issue?

Thank you,
Tanzil
