Hi Caspar,

If you converted from Freesurfer, rather than mapping independently in Caret, 
then this is puzzling.

I believe mris_convert can now convert directly to GIFTI (.gii) format, and I 
suspect this route might be more reliable than converting .w to .metric.  Have 
you tried this?  Probably easy and worth a shot.

As for the palete, your range needs to be compressed into the -1.0 to 1.0 
range, or in your case 0 to 1.
