Thanks again David...I've assigned classes in the ".foci" sheet...one
very very last question regarding your instructions here:
"If you assign one set of foci a 'class' [e.g., motion] and another set
of foci a different class [e.g., color], and then assign a distinct
color to each class, you can view them in distinct colors by selecting
Coloring Mode: Focus Class in the Foci Main Page."
How do I assign colors to classes? Can I use the "Names" column in the
".focicolor" sheet? Or do I need to go through a menu from the GUI?
thanks,
jessica

Thank you David...I started over and everything looks to be working now.
Good!
I was wondering if there is any info about how to estimate peaks as
spheres and then flatten them. I saw an article that did something to
this effect (Lewis, J., 2006, Cortical networks related to human use
of tools, The Neuroscientist, 12(3), p. 211). However, I couldn't
find any info on how to do this in the tutorials. Maybe there isn't
anything in which case I can try to figure something out myself.
The following steps may get you where you want to go. (There's not a
tutorial on this yet....)
Load the foci that you want 'painted' on the surface, and in the desired
colors.
Keep the left and right hemisphere foci as separate foci projection files.
[Notes: (i) If they are currently combined, they can be separated
by viewing the foci on just one hemisphere, then using the Foci: Delete
Foci Not Displayed on Main Window Surface. (ii) This can be a bit of a
pain, so a future modification may allow concurrent projection to left
and right hemispheres.]
Make sure that you have the appropriate PALS fiducial surface loaded.
If more than one is currently loaded, make sure the desired one is the
'active' fiducial surface using the Display Control: Surface
Miscellaneous: Active Fiducial pulldown.
Select Layers: Foci: Convert Uncertainty Limits to RGBpaint.
Choose the distances you want for lower, middle, and upper limits. The
default (upper limit = 10, the others = 0) is a good starting point.
Give the RGB Paint column name an appropriate header.
Press ok. It may take a few minutes if you have lots of foci.
View your results by choosing RGB Paint as a primary or secondary
overlay in the Display Control page.
Save the RGB paint file if you like it. You can create multiple columns
in a single file.

Hi David,
Sorry for inundating you with questions. I was wondering if it is
possible to have one study colored with two different colors depending
on the condition. I am trying to show all of one kind of effect in
one color and all of another kind in another color but sometimes both
of these kinds of effects come from one study. Is it possible to do
this?
Yes, indeed, by using the 'focus class' option.
If you assign one set of foci a 'class' [e.g., motion] and another set
of foci a different class [e.g., color], and then assign a distinct
color to each class, you can view them in distinct colors by selecting
Coloring Mode: Focus Class in the Foci Main Page.
To make the class assignments, you can either paste them in the Class
column when generating the initial (or revised) spreadsheet (the fastest
way) or you can enter the class one focus at a time using the Layers:
Foci: Map Stereotaxic Focus option. For the latter, press 'Edit
Number', then increment each number after entering the Class.
IMPORTANTLY, you have to press the Apply button after each entry in
order to save it; if you don't want to reproject the foci while you're
making these entries, DE-SELECT the 'automatic projection of foci'
button at the top.
thanks again,
jessica
p.s. I would spend more time to figure this stuff out myself but we
are doing a TICS paper that is due in a couple of weeks and I want to
use some figures like these.
I hope this works for you; I'd be interested in seeing a preprint (or at
least the relevant figures) at some point in the future.
