| I have conducted a block design fMRI study and performed a RFX analysis
| using SPM99.
| I got an interesting activation map and wanted to overlay it on a
| high-resolution stuructural image in order to identify acitve foci. My
| question is using the "single subject image" in the cannonical directory is
| a valid way to do it. Is this single subject image already normalized? I
| have normalized all the images to the EPI template. Should I coregister the
| single subject image to the EPI template, befor using it for overlay?
The single subject image has been normalised by a 9 parameter affine
transformation to the standard space of the templates. Although many
people superimpose results on this single subject brain, I prefer to
see them displayed on one of the average images.
All the best,
-John
