Hello, I have run recon-all on ~1600 participants and will use the aparc+aseg.mgz parcellation to extract structural connectomes.Across the dataset, the number of labels in each parcellations ranges from 109 to 115. Where can I find a complete list of labels in aparc+aseg.mgz?The distribution of missing labels is as follows: Label Region Name Missing Count72 5th-Ventricle 155280 non-WM-hypointensities 14903 Left-Cerebral-Cortex 97042 Right-Cerebral-Cortex 64230 Left-vessel 6662 Right-vessel 541006 ctx-lh-entorhinal 21016 ctx-lh-parahippocampal 22016 ctx-rh-parahippocampal 1 Among these, which missing labels are problematic? I assume the absence of the 5th ventricle and non-WM-hypointensities is expected, but I am uncertain about the others.I am only interested in the regions defined in the linked grey matter parcellations(https://secure-web.cisco.com/10fM6Wa2LmQzTYhwuqFhYwNe8hfPJWj90sm199DIWRN29TYfPn7J1NYMrz1FN2NGDMNFu-Xtcg8BOM3Y6dwN9YSBQIQX4-1jA_q6JSZKWl8lX2X3t1khfSfM9as3oozFSGtzJInaP1i3KsT6sElDq8YRb-nKCEBsO431iuJS9ORE6I3Wcfdkn3DkCaC6ET2ikTRteD2GuMRHrcrx0lJUp4KlONYc5h-Wz_MSJprI4zxE8R8-HQO6zpMAziWHsDRYlYXFkp4Rrd6f3n5n9Vd0HjXAAcLUp-pKo-7O5i5h-Y_Hc7IiFEMOaNSqMaoA9Hje1x7zxHeJBLuWm9EJYCWUlaA/https%3A%2F%2Fgithub.com%2FMRtrix3%2Fmrtrix3%2Fblob%2Fmaster%2Fshare%2Fmrtrix3%2Flabelconvert%2Ffs_default.txt) and will restrict my structural connectome extraction to those labels. However, do these missing labels above suggest segmentation issues?
