Using ROIs created by SPM with fMRIPrep data

Hi everyone,

I want to use anatomical masks generated using SPM WFUPickAtlas in a dataset preprocessed using fMRIPrep (MNI152NLin2009cAsymtemplate). Is the correct approach to register the spm12/canonical/avg152T1 to the fMRIPrep template and apply the resulting registration parameters to the ROI masks?

Thanks a lot!

Hey there,
To use anatomical masks generated with SPM WFUPickAtlas on data preprocessed with fMRIPrep (MNI152NLin2009cAsym template), follow these steps:

Register avg152T1 to fMRIPrep Template: Use a tool like ANTs or FSL to register the spm12/canonical/avg152T1 image to the MNI152NLin2009cAsym template.
Apply Registration Parameters to ROI Masks: Use the registration parameters obtained to transform your ROI masks so they align with the fMRIPrep preprocessed data.
