Susumu,<br><br>I just played with RoiEditor for a while, and found the atlas with the software. I am wondering if the tool (or you may recommend other tool) can use the atlas to label my subjects. Right now my subjects have been normalized to MNI152 space (non-linear registration), there are white matter lesions on some subjects, I want to calculate the lesion volume on the white matter regions. IF I can label my subjects, I will know the lesion volume on each parcellation. I do not have to need a very detailed label atlas at this point, maybe a atlas that can divide a brain into a few parcellations will be okay.<br>Thanks, any suggestion is high appreciated.<br>Best Regards,<br>Ping<br><br>Date: Sun, 25 Jan 2009 08:38:18 -0500<br>From: susumu@mri.jhu.edu<br>To: mristudio-users@mristudio.org<br>Subject: Re: [Mristudio-users] human brain atlas<br><br>

<p class="EC_MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">We have several white matter atlases in
lbam.med.jhmi.edu, but the easiest way is to download Landmarker/RoiEditor from
<a href="http://www.mristudio.org/">www.mristudio.org</a>, which come with
different types of electronic atlases. One of them is population-averaged atlas
in the MNI coordinates. If you use linear normalization, I recommend using this
atlas (named ICBM_DTI-81 for GE/Siemens and JHU-MNI-GA for Philips). If you use
highly non-linear normalization, I recommend the single-subject atlas (named
JHU-MNI-SS). Both atlases come with a hand-segmented white matter parcellation
map (WMPM). If you download RoiEditor, this software can apply the WMPM for
various types of image quantification. Please refer to <a href="http://www.mristudio.org/">www.mristudio.org</a> for more info.</span></font></p>

<br>
Could anyone recommend a brain atlas (label atlas) that covers the
main white matters? It will be great if this atlas is easy to
register to MNI template.<br>
<br>
Thanks a lot!<br>
