Dear experts,

Recently, I was using the GLM to test the relationship of "assortativity" and "clustering coefficient" with my symptom scores. Every time, when I load my design matrix, which was 2 columns and 67 rows ( the first column represents the subject, while the value is 1; the second column is PANSS score, while it was different according to the subjects),  and hit the start button, the same error "The design matrix has more predictor variables than observations." would show up on Matlab. But when I ran the correlation analysis with "degree" and "density" properties, there were no errors. Can you kindly help me solve this problem? Looking forward to your reply.

Best regards,
