Hello afni experts-

A quick question on 3dFDR- I was using the -cdep flag with a tlrc data set based on output from 3dANOVA. HOwever, the results seem to be over-corrected compared to other results that i obtained with alphasim (using a p of .001 and 250 ul volume). In the FDR analyses there were no values above 1.77. When I ran the same command using the -cind falg the results between FDR (thresholding at 1.96) and the spatial/parametric threshold analysis looked very similar.

Is the "i" in the cdep equation equal to the number of tlrc voxels (1 x1 x1) or equal to original number of voxels (4 x 4 x 5) as is the case in alphasim?


thanks in advance-

andy
