so i am running a simple one-simple ttest on my data but i noticed that only the first brick of the output gets saved(tried nifti and afni brick format,all has one volume). then i checked the afni help , followed this example:
3dUndump -dimen 128 128 32 -prefix ZZ
3dcalc -a ZZ+orig -b '1D: 14@0' -expr 'gran(1,1)' -prefix ZZ_1.nii -datum float
3dcalc -a ZZ+orig -b '1D: 10@0' -expr 'gran(0,1)' -prefix ZZ_0.nii -datum float
3dttest++ -setA ZZ_1.nii -setB ZZ_0.nii -prefix ZZtest.nii -no1sam
echo '=== mean of mean estimates follows, should be about 1 ==='
3dBrickStat -mean ZZtest.nii'[0]'
echo '=== mean of t-statistics follows, should be about 2.50149 ==='
3dBrickStat -mean ZZtest.nii'[1]'
\rm ZZ*
still i am getting one brick which is the mean image of the input.
any idea what's going on?
the compile date is Aug 5, 2013. is this the problem?
Thanks,
Tony
