AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

Sincerely, AFNI HQ

Hi,
I am running 3dMVM for a simple 1-way 3 group ANOVA and adding the post hoc ttests in the glt.
When I run the 3dMVM the fitt statpar for the ttest subbrik in the image header gives me degrees of freedom for the ANOVA, which differs from the fitt statpar if I run the same with 3dTtest++.

3dMVM
  -- At sub-brick #4 'DBSvCon:t' datum type is float:     -5.31884 to       4.19297
     statcode = fitt;  statpar = 100
vs
3dTtest++
  -- At sub-brick #1 'pat-con_Tstat' datum type is float:     -5.50756 to        5.5882
     statcode = fitt;  statpar = 38
the code for the 3dMVM is
3dMVM -prefix ${ResultsFolder}/${OutFile}.nii.gz \
-jobs 6 \
-mask ${MaskFile} \
-model "group" \
-num_glt 3 \
-gltLabel 1 DBSvR01 -gltCode 1 'group : 1*DBS -1*R01' \
-gltLabel 2 DBSvCon -gltCode 2 'group : 1*DBS -1*control' \
-gltLabel 3 R01vCon -gltCode 3 'group : 1*R01 -1*control' \
-cio \
-dataTable \
Subj	group	InputFile \
...

Is this what I should expect? or am I missing something?
The output image is the same just the thresholding is different.
thanks, Justin
