I have two quick questions about described in title.
I can find three txt file below which look like affine matrix /fmriprep_wf/single_subject_001_wf/func_preproc_task_rest_run_01_wf/bold_reg_wf/bbreg_wf/fsl2itk_inv/affine.txt
Would you tell me which one is the result of bbregister?
Second question is…
Is there EPI image which is resampled with the same matrix of T1w image?
I think this EPI image is the result of bbregister.
