HDF5 file output is not compatible with cellranger aggr v3 about cellbender HOT 9 CLOSED

@sjfleming I was aggregating reads from the same library prep on different flow cells (I ran CellBender i=on the .h5 output of cellranger aggr)

My original post is about using cellranger aggr on the outputs of CellBender. I ended up integrating them on Seurat.

Overall, what I found was running CellBender on cellranger aggr output and running CellBender on individual datasets then integrating in Seurat leads to almost identical output.

I am also about to test out CellBender remove-background on a couple 10X channels that I will want to aggregate, so I'm also interested in this issue. Thanks.

I tried running CellBender after cellranger aggr and it works fine

I am not sure if I totally understand, but I would be a bit cautious here... CellBender is really meant to be run on a per-sample level. If you are aggregating reads from different flow cell runs of the exact same library prep, you might be okay. But if you are aggregating anything else, I would urge you to run CellBender on the separate datasets first, and then aggregate them downstream.

@whelena Was your first post about trying to run CellBender on the .h5 output of cellranger aggr (this should run okay), or were you trying to run cellranger aggr on the outputs of CellBender (this has not been tested, but there are other ways to aggregate data from two experiments downstream, using scanpy or Seurat for instance)?

Hi,
I am wondering if this feature has been added to newer releases of CellBender? Can I aggregate multiple outputs of CellBender (raw.h5) using cellranger aggr?

Thank you for your help.

Hi @gauravgadhvi , sorry for the delayed response. I do not envision adding this functionality, because I do not think we would be able to. As I understand it, cellranger aggr now runs on the molecule_info.h5 files. These contain read-level information (as opposed to count matrix information collapsed to the level of UMIs). The count matrix (which is the input and output of CellBender) has less information than the molecule_info.h5 files which are needed for cellranger aggr to run.

I would recommend integrating separate samples, which have separately been run through CellBender, using scanpy or Seurat or whatever downstream single cell analysis tools you prefer. I personally never have a use case for cellranger aggr.

I am trying Cellbender on data from cell ranger 7.1.0 and I get the following error message (even after having checked the correct presence and compatibility of h5py and hdf5)/

Thanks for helping.

Hi @gvassart , based on the traceback, I gather you're running on a windows machine.

It seems to me like you have a problem with your installation of anndata. I'm seeing that the traceback seems to point to the line import anndata in cellbender/remove_background/data/dataset.py

Ultimately the problem points at your h5py installation not working correctly.

I would recommend trying this in your CellBender conda environment:

conda install -c conda-forge anndata
