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

First I use
3dDeconvolve -input sdr*.nii.gz \
-num_stimts 30 \
-polort A \
-stim_times 1 ${path}/location_1.1D 'SPMG2(0)' -stim_label 1 con1 -stim_maxlag 1 0 \
... ...
-fout \
-tout \
-bucket sm_SPMG2.nii.gz \
To point out the ROI of the each stimulate.Using SPMG, I can save each “cluster” as a Region of Interest (ROI).
Then :
3dDeconvolve -input sdr*.nii.gz \
-num_stimts 30 \
-polort A \
-stim_times 1 ${path}/location_1.1D 'CSPLIN(0,14,8)' -stim_label 1 con1 -stim_maxlag 1 0 \
... ...
-iresp 1 sm_location_1.nii.gz \
-iresp 2 sm_location_2.nii.gz \
-iresp 3 sm_location_3.nii.gz \
... ...
-fout \
-tout \
Use 3dMaskave + the “iresp” file + the ROI to get the average “iresp” for just one cluster(ROI)
Then to describe the Average Hemodynamic response PER ROI.


So I want to know if it is reasonable to use SPMG2(0) to find out all the stimulate area. And then use the CSPLIN(0,14,8) to predict the tend of the Average Hemodynamic response PER ROI.
Or I just need to use one to do them all.
