Ok, I will try it.
Thank you very much!

Hi Donna,
Wasn't SPM96 the single subject colin target? I'm asking, because I
really don't know the answer, but I think David may have told me
this while working on his foci project.
I don't know, but I will check it.
It turns out my caret/data_files/fmri_mapping_files directory *does*
have AVERAGE-FIDUCIAL_SPM95 and AVERAGE-FIDUCIAL_SPM96 spec files
that almost certainly have to do with David's foci project. Your
version may be older and not yet have these files.
Yes. I also have an AVERAGE-FIDUCIAL_SPM95. But I was wondering if it
exists an AVERAGE-FIDUCIAL_SPM99.
But a worthwhile task might be to do this:
cd /usr/local/caret/data_files/fmri_mapping_files
caret5
Then, open whichever of these specs you think has the best chance of
aligning:
Human.PALS_B12.LR.AVERAGE-FIDUCIAL_SPM95.LEFT.73730.spec
Human.PALS_B12.LR.AVERAGE-FIDUCIAL_SPM96.LEFT.73730.spec
Human.colin.SPM2.LEFT.71785.spec
Human.colin.SPM99.LEFT.71785.spec
Human.PALS_B12.LR.MULTI-FIDUCIAL_FLIRT_fMRI-MAPPER.B1-12.LEFT.73730.spec
Human.PALS_B12.LR.MULTI-FIDUCIAL_MRITOTAL_fMRI-MAPPER.B1-12.LEFT.73730.spec
Human.PALS_B12.LR.MULTI-FIDUCIAL_SPM2_fMRI-MAPPER.B1-12.LEFT.73730.spec
Human.PALS_B12.LR.MULTI-FIDUCIAL_SPM99_fMRI-MAPPER.B1-12.LEFT.73730.spec
Then File: Open Data File: Volume anatomy file: and open your
Marseille template
Switch to volume view ALL
D/C: overlay/underlay volume: settings: Toggle on Show surface
contour checkbox
Scroll around and evaluate how well the fiducial contour intersects
the surface
Ok. I will try it.
Finaly, if I choose to use a MULTI-FIDUCIAL spec, I will need to
project each individual metric to each Buck_Case01:12 surface?
After, how can I get an average fiducial map of the activations?
No: If you decide MULTI-FIDUCIAL_SPM99 aligns nicely, then select
SPM99 from the list of spaces in the Map to Atlas menu. Then you'll
see the entries that correspond to this spec file, select them, and
select either map to average fiducial only; map to each of the
subjects; and/or generate the average of the individual mappings.
In other words, the process is exactly the same; the only issue is
first determining whether any of the existing surfaces intersects your
template well enough, and if so, which intersects best.
Thank you very much.

Perhaps even get a capture, if the alignment is excellent, and use
this as your reason for using this target. If none align well, then
I don't have a good plan B for you.

Hello,
We have 18 subjects that have been analysed with spm99. Their
structural images have been normalized into a template from
Marseille
(http://irmfmrs.free.fr/formation/traitement_des_donnees/GuideSPM.htm)
in MNI space.
Since, we didn't use spm99 standard template, I am not sure we can
use
Human.PALS_B12.LR.MULTI-FIDUCIAL_SPM99_fMRI-MAPPER.B1-12.LEFT.73730.spec
for projecting the metrics. What would be the correct way of
projecting the metric files of those subjects into a Caret/PALS
surface?
Is there a
Human.PALS_B12.LR.AVERAGE-FIDUCIAL_SPM96.RIGHT.73730.spec for spm99?
Thank you for your help.
Mateus
