Hi Megan,

As Matthew mentioned in his reply, it is possible to view multiple hemispheres 
in the same window.  Each hemisphere must be in a separate spec file and when 
you load a second spec file, Caret allows one to append spec files.  When 
multiple spec files are loaded, there model selection control (below the 
toolbar) contains an "All Fiducial Surfaces" selection.  If you have both right 
and left hemispheres in the same spec file, load the spec file twice, once with 
left surfaces selected and the second time with right surfaces selected.

The vector file is in GIFTI (www.nitrc.org/projects/gifti) file format, 
although the vector file encoding has never been defined.  If you save the file 
in XML ASCII format you can load it into a text editor.  In the file are 
"DataArrays" with names Red, Green, and Blue which contain the red, green, and 
blue color components for each vector (the color component values range 0 to 
1).  If you have only a few vectors you could edit the color components.

If you are creating the vector file from an FSL volume (caret_command 
-volume-fsl-to-vector) there is an "-rgb" option that allows one to apply one 
color to all of the vectors.  

At this time, there are no options for adjusting the color components of 
vectors in Caret.
