Hi Afniers,
I have been investigating and dealing with t-values of FA on AFNI. I am trying to thresholding t-statistics image in order to zero all voxels that are smaller than a particular t-value (in my case, t = 3.372 corresponding to p-value, 0.005). However, I have experienced a weird thing when I adjust vertical bar to threshold OverLay image. Even though I do not reach 3.372 and just reach 3.309 as a threshold, a region whose voxel is 3.981812 is removed. I don't understand this.
Has anyone expereinced this issue? Your help in this would be greatly appreciated in advance.
Thank you.
