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.
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,

Dear AFNI experts,
Some time ago, we analyzed resting-state data using 3dGroupInCorr. We used this script
3dGroupInCorr \
-batch XYZ Bzdok_CoordinatesIRIec.txt \
-setA MM_RestingState_motion0.4.grpincorr.niml \
-labelA MM_Motion0.4 \
-unpooled \
-seedrad 5 \
-donocov \
-covariates Covariates_IRIec_grAge.txt \
-sendall
Which gave us the output that we wanted, namely the network of

Hi Rick,
I would like to know if there is a difference between my two groups in connectivity pattern between my seed and the rest of the brain that is modulated by IRI scores. Does this make sense? Would looking at the conjunction of the two maps answer this question?
Thank you!

Dear AFNI experts,
I ran the following command:
3dGroupInCorr \
-batch XYZ TPJ.txt \
-setA G1_RestingState.grpincorr.niml \
-setB G2_RestingState.grpincorr.niml \
-seedrad 5 \
-donocov \
-covariates Covariates_IRIec.txt \
-sendall
I am interested in looking at brain areas that are significantly correlated with the connectivity pattern in the temporoparietal junction as well as a s

Dear AFNI experts,
I am trying to run 3dGroupInCorr in batch mode. Other than the -help output from 3dGroupInCorr, is there a PDF document with more details?
Thank you,

Dear AFNI experts,
I pre-processed using afni_proc.py (example #11a) resting state data. I have two groups of participants (teenagers and adults). I am now looking into using the program 3dSetupGroupInCorr to set up the data to run 3dGroupInCorr.
In the documentation, it is mentioned that all datasets use the same mask. To be clear, I need to create a group mask that encompasses both teena

Dear AFNI experts,
I am trying to calculate the frame displacement (FD) according to the formula given in Power et al. 2012. The goal is to compare FD values between two groups. However, I have some doubts regarding how I can implement this with the output I have access to (the data is already analyzed). If I understand correctly, frame displacement represents the absolute value of displacemen

Dear AFNI experts,
I updated XQuartz today and now SUMA won't work. This is the error I get:
Error: attempt to add non-widget child "dsm" to parent " SUMA" which supports only widgets.
This is the output of the system_check:

Dear AFNI experts,
I have ROI masks (Nifti files) in MNI space (Colin 27 template). I would like to use them with the functional data I analyzed using the MNI_avg152T1+tlrc template.
I transformed the Nifti files into AFNI format, however, I am unsure as to what is the best way to transform my masks into the MNI_avg152T1template. I also need to change the voxel dimension from 1x1x1 to 2x2x2
