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:

https://discuss.afni.nimh.nih.gov

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.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hello Gang,

I am sorry to come back to that question.
There are a few things that are not clear yet on my side.
Here is the last update of the script:

3dLME -prefix 3dLME_glt.nii.gz -jobs 20 -mask brainmask_nolr_func.nii.gz \
-model "Sexe*age" -qVars "age" -ranEff "~1+age" -num_glt 4 \
-gltLabel 1 "05MF" -gltCode 1 "Sexe : 0.5*M +0.5*F age :" \
-gltLabel 2 "1MF" -gltCode 2 "Sexe : 1*M -1*F age :" \
-gltLabel 3 "1MF" -gltCode 3 "Sexe : 1*M age :" \
-gltLabel 4 "1F" -gltCode 4 "Sexe : 1*F age :" \
-dataTable @disign_matrix.txt -resid resid.nii.gz

disign_matrix look like
Subj	        age	     Sexe	InputFile
Oliver	1128.0	M	Oliver2019_02_02_correlations_fish.nii.gz
Oliver	1247.0	M	Oliver2019_06_01_correlations_fish.nii.gz
Pickle	1065.0	M	Pickle2019_02_02_correlations_fish.nii.gz
Pickle	1184.0	M	Pickle2019_06_01_correlations_fish.nii.gz
etc...


Here is the subrick obtained with the previous script after "3dinfo -verb"

  -- At sub-brick #0 '(Intercept)  F' datum type is float
     statcode = fift;  statpar = 1 53
  -- At sub-brick #1 'Sexe  F' datum type is float
     statcode = fift;  statpar = 1 6
  -- At sub-brick #2 'age  F' datum type is float
     statcode = fift;  statpar = 1 53
  -- At sub-brick #3 'Sexe:age  F' datum type is float
     statcode = fift;  statpar = 1 53
  -- At sub-brick #4 '05MF' datum type is float
  -- At sub-brick #5 '05MF Z' datum type is float
     statcode = fizt
  -- At sub-brick #6 '1MF' datum type is float
  -- At sub-brick #7 '1MF Z' datum type is float
     statcode = fizt
  -- At sub-brick #8 '1MF' datum type is float
  -- At sub-brick #9 '1MF Z' datum type is float
     statcode = fizt
  -- At sub-brick #10 '1F' datum type is float
  -- At sub-brick #11 '1F Z' datum type is float
     statcode = fizt

sub-brick 4, 6, 8, 10 are empty, is there a problem with "Sexe"? Am I supposed to use 0 and 1?

Just to be 100% sure, if I want to measure the overall age effect controlling for gender I just have to use subrick 4 and 5?
and then apply:
3dFWHMx
and
3dClustSim

Thank you!
Clément
