   <title>Request for segmentation label correspondence and additional gestational age atlases</title>
   <link>http://www.nitrc.org/forum/forum.php?thread_id=15810&amp;forum_id=10070</link>
   <description>&amp;lt;p&amp;gt;Dear Authors,&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;Thank you for providing the valuable fetal brain atlases. I am currently working on fetal MRI data analysis using your atlas, and I have successfully downloaded the data for gestational ages 23&amp;amp;ndash;25 weeks.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;However, I have a few questions and requests:&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;1. Segmentation Label Reference:&amp;lt;br&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp;In the segmentation folder (e.g., `GA23_seg.nii.gz`), I noticed that there is no accompanying file describing the meaning of each label value (e.g., 0 = background, 1 = CSF, etc.).&amp;lt;br&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp;Would it be possible for you to share the corresponding label list or a CSV file that maps the label values to anatomical structures?&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;2. Additional Atlases (GA26&amp;amp;ndash;38):&amp;lt;br&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp;Are there atlases available for the other gestational ages (e.g., GA26 to GA36)? If so, could you kindly provide access to those additional datasets or let me know how I can obtain them?&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;I truly appreciate your contributions to the community, and I would be very grateful for your guidance on this.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;Thank you in advance for your help!&amp;lt;/p&amp;gt;</description>
