Hi, I'm trying to understand what is happening under the hood in ETAC a bit better and noticed that there is a degrees of freedom adjustment that is performed that I do not understand.

Specifically, in lines 4685-4687:

if( do_Xclustsim && dofsub == 0 ){ dofsub = (int)rintf(0.0999f*(nval_AAA+nval_BBB)) ; }

When doing the permutations later, (if I understand correctly) -dofsub is used (lines 5379-5380):
if( dofsub != 0 ) sprintf( cmd+strlen(cmd) , " -dofsub %d",-dofsub) ;

Does this subtract DOF in the initial z stats that are computed but add DOF for the permutations? Could you help me understand why these two operations are needed? Thanks in advance.

dofsub is subtracted from the degrees of freedom computed from the number of samples (datasets - covariates - 1) in order to make the z-statistics -- computed from the t-statistics -- which are passed to 3dXClustSim (does the actual ETAC work) less significant. This adjustment makes the false positive rates of the ETAC multi-thresholding process be a little closer to their goals.

I'll add that I've been retired for 2 years now, and don't have precise memories of making this adjustment any more. Or about many of the inner details of AFNI.

Thanks so much for this response and for all of the work you've put into AFNI! The dofsub makes sense to me now, but I am still a bit confused why negative dofsub is used later in the code when doing the random sign tests:

if( dofsub != 0 ) sprintf( cmd+strlen(cmd) , " -dofsub %d",-dofsub) ;

I suppose this might not matter if the end results still appropriately control FWE as your paper shows.

Doesn't the -dofsub end up adding to the degrees of freedom. In my case, dofsub ends up being set to 2. In the initial z image that is created, -dofsub 2 is applied, but during the random sign tests, it instead runs -dofsub -2. I've pasted the full output of an ETAC run below in case that helps. The part that I am unsure of is this:

3dttest++ -DAFNI_AUTOMATIC_FDR=NO -DAFNI_DONT_LOGFILE=YES -RANDOMSIGN 360 -nomeans -toz
-seed 7920114 4381664 -nopermute -dofsub -2 -mask group_mask+tlrc.HEAD
-zskip 24 -setA RepeatPE_Etac.resid.nii
-prefix ./RepeatPE_Etac.0002.sdat &> /dev/null

Thanks again for any insight that you have!
