Hello,
The .tsv file containing the labels for the region segmentation shows 50 labels:
However, the segmentation file *_desc-drawem87_space-T2w_desg contains 87 labels. According to Makropoulos et al, 2014:
The 50 atlas labels are subdivided into 87 labels. Once the EM estimation presented in the next section has converged, we merge the subdivided parts of the structures.
I would like to know if there is a resource where I can make sure each label is the high/low intensity variety of certain other label. I should mention that Robinson et al, 2018 states:
The resulting segmentation contains 87 regional structures (see [Table 1]). These are merged to further produce the following files: tissue labels, left/right white surface masks and left/right pial surface masks.
With Table 1 not being helpful, since it contains the 9 tissue types.
Thank you for any help with this issue.
Diego
