Dear caret experts!
Happy New Year!
I am trying to map a functional volume to a surface via Munu*: Attributes:
Map Volume(s) to Surface(s)*.
I chose *Map to Caret With Atlas* with the following options: Space: *SPM2*;
Atlas: *PALS_B12 Multi-Fid Map LEFT hemisphere (73730 nodes), SPM2 space*
This means the functional volume will be mapped to the left hemisphere
surface.
However, when I see the results, I can see activations on the right
hemisphere.
[Page Selection: *Overlay/Underlay - Surface*: *Primary Overlay: Metric*:
MFM LEFT - SPM_T_0001.hdr]. I clicked on Toollbar: *Model*: *FIDUCIAL Human.
PALS_B12.RIGHT_AVG_B1-12.FIDUCIAL_SPM2.clean.73730.coord* to see if there is
any activation on the right hemisphere. Surprisingly, I see the activation
on the right hemisphere!
Why the activation appears on the right hemisphere even I just mapped the
volume to the left hemisphere surface? [*PALS_B12 Multi-Fid Map LEFT
hemisphere (73730 nodes), SPM2 space]* Must I just ignore the activation on
the right hemisphere? Thank you very much!
Best wishes!
Yours Sincerely,
YAN Chao-Gan
