RE: importing existing connectivity matrices in CONN
Dear Jaron,
The .mtx.nii file appears perfectly fine (except perhaps matrix #93 which appears to contain a lot of missing values), so using a design matrix with 50 rows and any arbitrary number of columns should have worked perfectly fine. Could you please double-check and/or share the form of the conn_module command that you used and in particular the choice of 'design_matrix' field entered?
Best
Alfonso

Thanks for your prompt response. We tried to to run the functions you mentioned. We managed to convert our matrix into NIFTI format using "conn_mtx_write". However, when we tried to run our group-level analysis using "conn_module", we got an error message that there is a mismatch in the number of subjects in the design matrix. CONN only finds 1 subject whereas our design matrix contains a total of 100 subjects (2 times 50 subjects for 2 different conditions). I attach the matrix and the error message.
Thanks in advance.
