Hi Nan,
1. Identifying a focus or two among a forest of foci: If you know the name of
the focus, you use D/C: page dropdown = Foci Name to toggle all off, then
toggle on just the ones you want. If you don't know their names, then you can
save the foci file as a csv file and use a spreadsheet or other sort utility to
sort on the x, y, or z position field. This will make it easier to find the
focus that corresponds to your special location. Then use the name value in
that row to toggle on just the focus (or two) that you want.
2. Making both hemispheres appear in the same caret window (these instructions
courtesy of Tara Smyser, who said she got them from Jim Alexopoulos):
a. Load the first hemisphere
b. Load the second hemisphere. During this load a window will pop up with a
button that asks whether you want to keep the initial loaded spec file. Click
on this button.
c. You will then see the second hemisphere you loaded in the caret window. At
the top of this window there is the Model drop down menu. Click on this drop
down and select the All Fiducial Surfaces Tab. This will display both
hemispheres in the same window.
3. Getting connections to display from one focus to another: I don't know how
to do this. Someone told me you can use vector files to do this, but that is
the extent of my knowledge. This BrainNet Viewer looks specifically designed
for that purpose, but I know nothing more about it than what this page shows:
