<br>
I am working on a small project with the adhd data. My
background is software engineering, but I am very new to
nipy and neuroscience in general so I might get some
terminology wrong.<br>
<br>
Currently I am working my way through the
correlation/connectome examples. I have a few doubts but, in
order to keep it simple, I will just <br>
post a couple, hoping for help.<br>

You're probably using Nilearn. Could you post these questions on
Neurostars.org, so that other people can benefit from the answers ?<br>

1. The fetch_adhd functions states that a maximum of 40
subjects can be retrieved. This means that if I want to use
more, I need to do all the processing myself from the files
at <br>
<a href="https://www.nitrc.org" moz-do-not-send="true">https://www.nitrc.org</a>.
Is it correct? <br>

provides some atlases and I have more or less understood how
to use them. However, on NITRC one can also find 2
functional parcellation templates, and time series are
provided <br>
for those parcellations. I think I managed to create and
display connectomes with those templates but, what if I want
to know the label of a region? Those regions are labelled by
numbers.<br>
For example, if I use the aal atlas, I can see
'Precentral_L', 'Precental_R' and so on. Can I do the same
with the cc200 for example? I fear that, since those
parcellation are functional <br>
and not anatomical, there are no real labels associated to
the region. But I would still like to have a data-structure
that allows me to query things like: this region is in V1,
or in the <br>
frontal lobe or other.<br>

<p>The best way to learn about parcellations is to run the
corresponding examples of the library.</p>
<p>Each atlas comes with different information, so you may not have
functional labels if the atlas comes from a functional
parcellation, such as resting-state for instance.</p>
