Yep I had in mind the following suggestion:
- an additional file.
- an additional webpage on the main site.
- on the wiki page of the repository.

Participants site are the hospital where the acquisition have been done.
from autism.
I see.
@GaelVaroquaux Do you think that it should be added in a sort of introduction in the notebook or shall we have a wiki or an aside page info for those features. I am scared to clutter the notebook by adding up information.
from autism.
@vfdev-5 you can let this issue opened. This is actually useful and this is not a duplicate.

@suprsankr
those measures are volume because they are not in the cortex (only cortical area are defined between 2 surface which allow the quantification of mean thickness and area)
from autism.
I second that. Domain knowledge would be very helpful for this challenge as there are people that are not familiar with the description of features.
from autism.
@alirezamosh check also the website. If you have more questions we can discuss in more details.

@glemaitre concerning "anatomy" features this site has been already sited in one of the issues. Maybe it would good to include it as a reference for those who is not famiiliar with the domain.

Another question for brain anatomy specialists, according to wiki it seems there are 4 ventricles:
- lateral ventricles right and left (one for each hemisphere)
- third ventricle
- fourth ventricle
However in the data we have also anatomy_5th-Ventricle
column with data like:
EDIT: seems FreeSurfer speaks about the 5th ventrice too :
BrainSegNotVent - same as BrainSeg without ventricles (lateral, inferior lateral, 3rd, 4th, 5th), CSF, and choroid plexus.
from autism.
@vfdev-5 You are right. The extraction was done with FreeSurfer so you will find information there regarding the anatomy.

For more info on fsMRI, connectivity I found the article "Learning and comparing functional connectomes across subjects" and "Nilearn docs" somehow helpful.

@romainVala thank you! i did not quite understand the second part of the answer. The above measures are also volume measures (such as anatomy_Optic-Chiasm..) except that they are not part of the cortex. So these regions cannot conveniently be measured for a thickness and area measure.
However for a non brain scientist, it suffices to know that the above measures are just volume measures. correct ? :)
