TENX98 and TENX97 don't have pixel/array coordinates #28

Closed KalinNonchev closed 3 months ago

KalinNonchev commented 3 months ago

Hi, thank you for providing these valuable datasets. I have been exploring the breast cancer IDC dataset and noticed that samples TENX98 and TENX97 do not have pixel and array coordinates in their obs metadata. Could you clarify whether these coordinates are missing, or if this might be due to a preprocessing error? Thank you in advance! Best,

Hello Kalin, For now we store the spot coordinates in the obsm['spatial'] for compatibility with some core scanpy methods such as sc.pl.spatial. First column and second column in obsm['spatial'] are x and y pixel coordinate in the full resolution H&E respectively.

Ok, I wrongly assumed that I would be able to find this also in the obs for all samples (named as array_row; array_col, pxl_row_in_fullres, pxl_col_in_fullres). Thanks
