Thank you! I have been able to get my post-fmriprep processing pipeline to work well. However, now I have a related question. I am using 3Dclusterize to list clusters over a certain threshold, and I would like to list them in MNI space. I have read on another thread (https://afni.nimh.nih.gov/afni/community/board/read.php?1,161972,161980) that 3dclusterize is supposed to know whether your data are in MNI or Talairach space. Because I did first and second level processing in AFNI, my data files have the suffix _tlrc, but they were registered by fmriprep in MNI space. 3Dclusterize is printing out Talairach space coordinates. Is there a way for me to directly tell 3dclusterize that these data are actually in MNI space? Thanks in advance for your help!
