[caret-users] orientation flip seems to occur in Caret?

 Dear Caret users,

 I compare the surface render view of caret to that of SPM and suspect 
orientation of SPM T map file may have been flipped when it was 
projected onto
 the template spec file 
(Human.PALS_B12.BOTH.TEMPLATE-for-fMRI-MAPPING.73730.spec)
 My SPM has neurlogical convention (L-L / R-R) and it shows more 
activation voxels on the right side, whereas eye-balling of flat map in 
caret suggests that   there are more voxels on the left side. I'm 
wondering why this happened and I need to change the convention somewhere.
 Enclosed are two screen captured files showing the caret and SPM view 
side by side.
 Any help would be greatly appreciated.

Thanks,
 YSL
