Dear AFNI experts,

I was doing pretest for SEM analysis with time series (250 time points) from 3 ROIs at each subject (2 subjects) So I run SEM_script using a command like below.

tcsh -x AFNI_SEM_script_treegrowth.csh c03.1D c05.1D thetas.1D

Unfortunately, I face an error message at very begining of process of SEM.

thetas.1D is below

# RIFG RIFG2 RIns
RIFG 0 2 2
RIFG2 2 0 2
RIns 2 2 0

#One of timeseries files,c03.1D, for 2 subjects is like below.
7465.09 7273.43 11149.5

7556.84 7364.05 11151.7

7434.16 7281.24 11201.4

7377.94 7332.38 11123.7

7451.46 7273.34 11150.6

7530.23 7252.7 11251.2

7490.49 7288.49 11198.1
