Dear AFNI experts,
We would like to visualize our results with Cluster Explorer. It seems that it does not work if the output of 3dttest++ is z-score. I have tried to convert the z-score to t-score by using 3dcal with the following expression:
3dcalc -a TTEST_one_sample.nii -expr 'cdf2stat(stat2cdf(a,5,0,0,0),3,13,0,0)' -prefix TTEST_one_sample_tstat.nii
Although the function run, the output does not correspond to the t-stat.
Could you indicate me what is wrong in this expression?
Thanks a lot in advance.
Karel
