Hi Donna,
Thank you very much for your quick response. I can get the report you
suggested, but it's not quite what I need. What I'm looking for is
something that gives me mean metric values over paint areas, as you get
when you select individual paint regions and then create statistics.
Does Caret include an option to do that?
Thanks,
Johannes

Hi Johannes,
Try using statistical report on selected nodes instead. Below is an
example for another user that might help:
When you use Statistical Report on Paint Subregions, whatever column you
have selected on the ROI menu is affecting the areas reported for each
column. If you select the CS of subject A's paint column, then that
subject/column will have no ??? area listed, e.g.:
Paint Column 0 deformed CS 1
Paint Name Area Percent Area COG -
X COG - Y COG - Z Latitude Longitude
CS 2107.198 100.000
31.448 -22.408 54.292 0.000 0.000
But each of the other subjects' non-selected columns has its paint split
into overlap and non-overlap areas:
Paint Column 29 deformed CS 30
Paint Name Area Percent Area COG -
X COG - Y COG - Z Latitude Longitude
??? 287.918 13.664
30.901 -22.159 61.147 0.000 0.000
CS 1819.280 86.336
31.548 -22.453 53.045 0.000 0.000
This could work to your advantage if you have a centroid paint
selected. Then it will report the percent overlap for each subject.
But if you want the real CS area for each subject, select all nodes and
use statistical report on selected nodes.

Hi folks,
I'd like to extract stats for individual Brodmann regions (warped from
the Colin atlas to an individual) from a functional experiment. I can
query each individual region, but that's tedious and I was hoping that
Caret's "Statistical Report on Paint Subregions" would do the trick
(see screenshot). Unfortunately, the resulting report only contains
data for one entry of my Paint file, BROD.UNASSIGNED. I'm running
v.5.503, fresh from the web. Maybe I'm misinterpreting what this
option is supposed to do? All hints appreciated!
Thanks a lot,
Johannes
