Hi, John:

Thanks for your help. I will ask senior students if they are able to write
NIFTI Volumes (.nii).

For .hdr files, I have followed your instructions.
After mapping .hdr to Surface, It looks better than before (
http://midodo.net/neuro/caret2/capture.tiff) but it doesn't look as perfect
as what you did yesterday (the attached file: pastedGraphic.tiff).
The right spotlight (22, 54, 4) seems to be not as bright as
"pastedGraphic.tiff" does.

I took the screenshots step-by-step:

Did I do something wrong or set improper parameters?

Thank you very much.
