Hello all,
I would like to convert a nifti volume (3D+time) with p-values from a Student's T-distribution into t-values. With this goal in mind, I tried:
3dcalc -a nifti_name.nii -expr 'fitt_p2t(a,df)' -prefix output.nii
where df is the number of degrees of freedom.
However, the output volume is all zeros.
Does anybody know what the problem is and how to solve it?
Thanks
Cesar
