format problem with raceID

Dear members,

I would like to know should I proceed with the following. I download on the HCA the raw counts matrix:
https://s3.amazonaws.com/preview-ica-expression-data/ica_bone_marrow_h5.h5

However, has you can see the format is a h5 -> not compatible with raceID tool, or at least not this one. someone told me to transform it into a h5ad but the result is the same … it is not working.

I could download as well the whole experiment with the tool Human Cell Atlas Matrix Downloader but then I got 10BG of data and no tool to filter per row and not per column?

So could you tell me how I should proceed?

Thank you in advance
