Sorry to hear that you are sick Donna. and thank you for replying promptly! The problem is I was using SPM8 to normalize my data into their EPI template, and the spec i found recommended by caret was "the Human.PALS_B12.BOTH.TEMPLATE-for-fMRI-MAPPING.73730.spec" or MGH group was " PALS.B12.BOTH-HEMS.For-Stereotaxic-foci-analyses.73730.spec". For both I tried, and the space I chose SPM5, as there is no SPM8. But weirdly, for atlas under SPM5, there is only left human.pals.multi.fidmap.Left.hemisphere.73730, but no corresponding human.pals.multi.fidmap.right.hemisphere.73730...
Do you think the choices I made were reasonable, and do you know where I can find the right hemisphere atlas for SPM5 that associate with a specific spec file good for fmri mapping using SPM8? Thank you again and hope you feel better!
