Hi there,
The Allen atlas has fine substructures for some regions (e.g. subregions of SCig, here).
I can find the structure ids associated with them, for example with the below code
scm_sub_acronyms = ['SCig-a', 'SCdg']
fine_substructures = structure_tree.get_structures_by_acronym(scm_sub_acronyms)
However, there are not structure masks for these fine substructures available on this page. I.e. structure_494.nrrd is not listed.
Hence, when I run the below I get an error
for i, s in enumerate(fine_substructures, start=1):
mask, _ = mcc.get_structure_mask(s['id'])
The error tells me
HTTPError: 404 Client Error: Not Found for url: https://download.alleninstitute.org/informatics-archive/current-release/mouse_ccf/annotation/ccf_2017/structure_masks/structure_masks_50/structure_494.nrrd
Are there structure masks available for these fine substructures elsewhere? Or is there any alternative means of creating them?
494 is not present at 10um resolution in the annotation volumes for the 2017 or 2022 CCF
Thanks
