One and two-sample t-tests for f/ALFF

Submitted by allanw on Wed, 03/18/2015 - 01:05

Hi All,

I processed a group of patients and controls in DPARSF, and now I have a results folder containing ALFF and fALFF folders. Inside each folder I have files of the form ALFFMap, mALFF-1Map, mALFFMap, and zALFFMAP. I want to do one-sample and two-sample t-tests for each group, so which type of file do I use? The statistical analysis will be performed using REST v1.8.

Thanks in advance for the help!
Allan

Re: One and two-sample t-tests for f/ALFF

you can select any group from mALFF-1, mALFF and zALFF to perform one-sample or two-sample t-tests. When performing one-sample t, the base are 0, 1 and 0 separately.
