Dear Caret experts,
I've been using Caret to map the connectivity results, and just notice that
the patterns always look the same on both hemisphere, even when I know there
is no DLPFC on the left hemisphere but only on right hemisphere, (which is
validated by overlaying them on MRICron, but it just look the same on
CARET!
Here is what I did:
1. generate NIFTI format filr for thresholded spmT.hdr file
2. menu-attribute- map volume to surface-metric(function) surface data->add
volumes from disk->map spec file with atlas->choose " PALS.B12.*BOTH*-*
HEMS.For-*Stereotaxic-foci-analyses.73730.spec", space " SPM5" (as I
processed everything in SPM8), atlas "
PALS.B12.*BOTH*-*HEMS.For-*Stereotaxic-foci-analyses.73730.spec".->enclosing
voxel.
3. view results, I loaded the metric and spec file, primary overlay
("metric"), then model I chose
"fiducial.human.pals_B12.Left.Average.B1-12.fiducial_moritotal_clean.73730.coord".
Then change the model to
"fiducial.human.pals_B12.right.Average.B1-12.fiducial_moritotal_clean.73730.coord".
They look the same, even with different metric setting ( like threshold
selection)
Could you help me figure out what did I do wrong? Thank you!
Best,
