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

Hi, Pt,

One more question:

On your example script, 1) the input for "-inset" (in your example, it is "REST_in_DWI.nii.gz "). As I said before, I assume that this script can be for both rest-state fMRI and task based fMRI. With regard to the input file, I do not exactly know your meaning of the 4D data. I think it should be the output from the standardized preprocessing (i.e., the input is the same to those for the 3dDeconvolve step). We do this for each subject. Am I correct? Or it should be the output from the 3dDeconvolve step?

Since we do it one subject by one subject, we then have to extract the mean data from the whole group subjects - We can get the mean from all of the subjects. Is this method correct?

2) the input for the "-in_rois" (in your example, it is "ROI_ICMAP_GM+orig"). I assume that we can just put several ROIs together and get this file. For instance, I can get it via this way.
3dcalc -a 'TT_Daemon::amygdala' -b 'TT_Daemon::Hippocampus' .... -expr 'step(a)+2*step(b)+3*step(c)+....' -prefix ROI_ICMAP

3) the input for the mask, I can get it from the mean of all subjects.. Or we can just use NN27 or something else?
For instance, I can get it from this way.
3dmask_tool -input Sub*/*BrainMask+tlrc.HEAD \
-prefix mask_overlap.7 \
-frac 0.7

Could you correct me if I am wrong?
Thank you very much,
J
