Request for segmentation label correspondence and additional gestational age atlases

Dear Authors,


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 23–25 weeks.


However, I have a few questions and requests:


1. Segmentation Label Reference:
   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.).
   Would it be possible for you to share the corresponding label list or a CSV file that maps the label values to anatomical structures?


2. Additional Atlases (GA26–38):
   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?


I truly appreciate your contributions to the community, and I would be very grateful for your guidance on this.


Thank you in advance for your help!
