Hi, AFNI experts,
When I use paired 3dtest++ to analyse my group data between eyes open(EO) and eyes closed(EC) which is within subject, I want to add head motion as covariates. Therefore, I calculate averaged motion across all TRs in each subject’s condition(EC and EO). And I got 6 number for each subject’s condition,represented for 6 motion parametric(roll, pitch ,yaw,ds ,dl,dp).Then, I calculate absolute value of making EC averaged motion subtract EC averaged motion in every subject. Finally, I got a list of 6 averaged motion parametric of EC-EO for all subject. Here is the data table,which file name is ‘motion_cov_ECvEO_del03.txt’.

And when I use this data table in 3dttest++, it occur these error messages:
++ option -setA :: processing as LONG form (label label dset label dset …)
++ option -setB :: processing as LONG form (label label dset label dset …)
++ Mixed Table: processing file /media/hjr/Elements/fMRI_berlin/result/motion_cov_ECvEO_del03.txt

** FATAL ERROR: Can’t continue after the above error!
