Dear afni experts,
3dMEMA execution halts after the following lines:

Have lop$centerType 1
Have lop$centerType2 0
Have lop$centerVal[jj] 25
Have lop$centerVal[jj] 26
Error in cbind(lop$xMat, lop$covData) :
number of rows of matrices must match (see arg 2)
Calls: process.MEMA.opts -> as.matrix -> cbind
Execution halted

kindly help me figure what am i doing wrong here?

My covariate table looks some thing like this: (There are 98 subjects in total)
subj Age Edu
042 24 17
044 27 16
079 24 25

The 3dMEMA script looks something like this:

3dMEMA -prefix $results_dir/P-H \
-mask $mask_dset \
-groups HC PT \
-covariates /mnt/e/MROT_CLEANED/Covar_MEMA_FIXED.txt \
-covariates_center cov1 = 25 26 cov2 = 16 15 -covariates_model \
center=different slope=same \
-set HC \
042 "$dirA/C0042.results/stats.C0042_REML+tlrc[7]" \
"$dirA/C0042.results/stats.C0042_REML+tlrc[8]" \
043 "$dirA/C0043.results/stats.C0043_REML+tlrc[7]" \
"$dirA/C0043.results/stats.C0043_REML+tlrc[8]" \
046 "$dirA/C0046.results/stats.C0046_REML+tlrc[7]" \

"$dirA/C0047.results/stats.C0047_REML+tlrc[8]" \
(goes on.....)
