[caret-users] t-test iteration quits

[Akiko Ikkai]

Hi,

I'm trying to run one-sample t-test from the command line, and having this strange problem of iteration quitting at 16th permutation, or fewer. If I give iteration fewer than 16, it runs fine, but anything above it, it quits at 16. I can't seem to find where this magic number 16 is coming from. Below is the command I'm running:

for EACHMETRIC in `ls *LH*.metric`; 
do 
/usr/local/caret-5.51/bin/caret_command -metric-or-shape-stat-one-sample-t-test ${EACHMETRIC} /hyper/library/caret_files/Human.PALS_B12.LEFT_AVG_B1-12.FIDUCIAL_711-2C.clean.align.73730.coord /hyper/library/caret_files/Human.sphere_6.LEFT_HEM.73730.topo /hyper/library/caret_files/deformed.Human.LH.Group.surface_shape 3 T-Map_${EACHMETRIC} Permuted_T-Map_${EACHMETRIC} `basename ${EACHMETRIC} .metric`.paint T-Stats_`basename ${EACHMETRIC} .metric`.metric T-Stats_`basename ${EACHMETRIC} .metric`.txt -2.5 2.5 0.1 10 1 100 0 4 ; 
done

we are running caret version 5.51 on Mac. 
... any insights?

Thanks in advance! Akiko
