Hi AFNI Gurus!
I would like to make a resting state FC mask of the top 10% of correlations in a single subject using 3dClust or 3dMerge. In other words, I would like to use percentile thresholding instead of p-value thresholding. This can easily be visualized in the GUI by simply checking the "percentile threshold" box and placing the sliding threshold to 0.90. However, I am having trouble identifying how to do this with 3dClust or 3dMerge in the command line.
Is there an option or work around for this? Thanks!!
