I have some questions regarding the display of 3DFDR images. I am assuming that the number below the Z-slider is the q-value. It seems to me that if I am working at an alpha of 0.05, I still need to figure out where the q-line intersects the p-values (as per the Genovese paper). I can do that from the listing provided by 3dFDR's output of the index,p,q, and Z values. Once I know this, I can set the z-value slider to a value that corresponds with the q-value calculated above. The indicated Z-value is then the FDR. Am I correct? Please help if I have got this completely wrong.
