> may I know if the output F-statistics in 3dANOVA3 are normalized in the volume?
You can convert an F-statistic sub-brick to Z-statistic with the following steps:
1) find out the numerator and denominator degrees of freedom for the F-statistic sub-brick
3dAttribute BRICK_STATAUX myFile+tlrc'[##]'
where ## is the F-statistic sub-brick number.
2) run
3dcalc -a myFile+tlrc'[##]' -expr 'fizt_p2t(fift_t2p(a,N1,N2))' -prefix outputFileName
where ## is the F-statistic sub-brick number, and 'N1' and 'N2' are the numerator and denominator degrees of freedom from 1) above.
