I have had a look at those tutorials, but I was hoping to bypass the whole meta-data entry. All other potential solutions do not seem to do the trick. I have noticed one thing though. In following the dated guide I cited in my first email, I read a csv spreadsheet containing the foci into Caret that had the following format:
tag-version 1 tag-number-of-cells 20 tag-number-of-comments 3 tag-BEGIN-DATA 0 x y z Study1 0 1 x y z Study1 0 2 x y z Study2 1 3 x y z Study2 1 ... 0 SPM2 1 SPM99 In the Map Stereotaxic focus dialog, I then assigned the stereotaxic space in the 'Studies' dialog based on on the labelling at the bottom (e.g., 0 = SPM2, 1=SPM99). I cliked 'Apply' for each focus and then tried to project them using Project Foci to PALS atlas. It seemed to progress to completion without errors, but I cannot visualize the foci. I've noticed however, that if I close Caret, re-open it then try Project Foci to PALS atlas again, it tells me that the foci do not have an associated stereotaxic space. I'm guessing there is something wrong in the way I'm assigning the space.
