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 afni experts,

I have to run my afni pipeline in two steps as I want to take the data after preprocessing and run wavelet despiking on it, and bring it then back to afni to run the regress block (for nuisance regression for resting state analysis). My problem is that for some reasons 3dDeconvolve does not calculate the demean and derivative from the motion regressors. What am I missing in my command? Maybe I need to run 1d_tool.p and calculate the -demean and -derivative before 3dDeconvolve?
(The directory where I run this command includes the despiked dataset, and the dfile_rall.1D file)

I am using the following afni_proc.py command for the regression

afni_proc.py -subj_id ${subj}\
-script proc.py_scripts2/proc_${subj}.sh\
-out_dir ${top_dir}${subj}/${subj}.3dDeconvolve\
-dsets ${func_dir}pb04.P1002.scale_masked_Despiked_wds.nii.gz\
-blocks regress\
-regress_apply_mot_types demean deriv\
-regress_extra_ortvec ${stim_times_dir}cwm.1D ${stim_times_dir}ccsf.1D\
-regress_extra_ortvec_labels cwm ccsf
