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,

I am trying to extract time series and am using the command below:
3dmaskave -q -mask /Volumes/masks/SN_resam.nii.gz \
func_task_pp_ICAaroma_bptf.nii.gz \
> /Volumes/subjects/${subj}/${subj}_SN.1D

However, am getting the error:
Input dataset func_task_pp_ICAaroma_bptf.nii.gz grid mismatch from mask.
*** Input and mask datasets are not same dimensions!

I've tried the following:
3dinfo -header_line -prefix -same_all_grid /Volumes/masks/SN_resam.nii.gz /Volumes/K99_Data/${subj}/restingHCP/func_task_pp_ICAaroma_bptf.nii.gz
3dmaskave -q -mask /Volumes/masks/SN_resam.nii.gz \
func_task_pp_ICAaroma_bptf.nii.gz \
> /Volumes/subjects/${subj}/${subj}_SN.1D

And received the following message:
prefix =dim? =delt? =ornt? =cent? =obl?
SN_resam.nii.gz 0 1 1 0 1
func_task_pp_ICAaroma_bptf.nii.gz 0 1 1 0 1
++ 3dmaskave: AFNI version=AFNI_21.3.17 (Dec 30 2021) [64-bit]
*+ WARNING: Input dataset func_task_pp_ICAaroma_bptf.nii.gz grid mismatch from mask.
Try the following command for grid comparison:
3dinfo -header_line -prefix -same_all_grid /Volumes/masks/SN_resam.nii.gz /Volumes/K99_Data/${subj}/restingHCP/func_task_pp_ICAaroma_bptf.nii.gz

Can you please advise?? Thank you so much!
