[caret-users] Projection foci

[John Harwell]

Alex,

To project foci to the PALS atlas, the foci must be linked to studies  
with valid stereotaxic spaces.  The stereotaxic space determines which  
of the surfaces inside of the Caret distribution are used to project  
the focus.  Studies are edited using the Attributes Menu->Study  
Metadata->Edit Studies Dialog.  There is some documentation on this  
dialog at "http://brainmap.wustl.edu/caret/caret_help/dialogs/study_metadata.html 
".

Once studies have been entered, return to the Map Stereotaxic Focus  
Dialog and use the edit mode.  Pressing the Study Metadata Button  
allows one to choose the appropriate study for the focus.  After  
linking the study to the focus press the Apply button and the focus  
should be properly projected.
