I’m working with two SEA-AD MERFISH files from the spatial-transcriptomics bucket: medial-entorhinal-cortex/combined_anndata_object/1444201261_MEC_mapped.h5ad andhippocampus/combined_anndata_object/1444211893_HPF_mapped.h5ad.
The obs in these combined objects contains only cell-type annotations and spatial coordinates — no Donor ID / Specimen Barcode / Section columns like the MTG MERFISH release has, and there’s no per-donor folder in the S3 path (unlike the caudate region). How do I map these specimens/cells to their donor(s) (H20.33.xxx)? Specifically: is each combined file a single donor, or are multiple donors pooled — and if pooled, where are the per-cell donor labels?
Thanks!
