Hi Nicola,
Your .hdr file is missing this origin information:
SPM originator decodes to 40 57 26
Try writing the volume out in NIfTI format and mapping it in Caret;
you'll have better luck (I hope). There are other work-arounds if this
fails, but this is a classic example of why NIfTI was invented.
I confess two things:
1. I haven't personally switched over to NIfTI yet. I really, really
should. I'm just mid-project in so many projects now.
2. I haven't yet created SPM5 versions of the PALS surfaces. I'm
hoping they don't differ much from SPM2.
This page illustrates how results from mapping to SPM99 differ from SPM2:

Subject: mapping SPM5 functional results onto PALS atlas

Dear experts,
I am trying to map functional data obtained with SPM5 (the attached *.img
+ *.hdr) onto a flattened image of the left hemisphere (the PALS B.12),
using Caret 5.4 (attributes: map volumes(s) to surface(s)). I remember I
could do it easily on SPM2-data using Caret 5.3, but now I get the
following error message (and no mapping of the functional data):
You have selected a ".hdr" file. If this ".hdr" file does not contain an
SPM generator, it is unlikely that it will get mapped to the surface
correctly.
I searched through the tutorials but I could not find a solution to this
problem. Any suggestions would be greatly appreciated..
Many thanks in advance,
nicola
