Need help to interpret Cortical fold morphometric attributes
Posted: Tue Apr 05, 2016 4:37 pm
Hi all,
I am looking for any documentation regarding cortical fold attributes (as well as edge attributes).
I read a cortical graph by using aims library in python, and get a list of folds - each of them has a list of attributes attached. Some attributes are intuitive and easy to interpret, but others are not (at least for me)...
For example,
- what exactly 'size' measures (there are other attributes, such as surface area and various volumes, so how the size attribute differs?)
- how exactly the depth and thickness attributes relate?
- what are the moments?
- what is the difference between 'hull_normal' and 'normal' directions?
- what does a direction weight mean (i.e. 'hull_normal_weight')?
- what 'direction' is (there are already hull_direction, normal, and normal_hull, so what does this 4th direction attribute mean?)
etc.
After desperately searching the documentation online, I could not find answers to these questions.
I would highly appreciate if anyone could please point to any available documentation, or even properly commented source file where I could read about folds and edges attributes.
Thanks ahead,
Ruslana.
