Thanks for the data! That was super helpful for working out what the issue was. I have tracked it down to the `colPairs()` function in the **{SingleCellExperiment}** package and have...

Hi @spatts14 I think there could be two issues here but let's look at the original one first as I thought I had solved that already. It looks like the...

Hi @ScreachingFire Thanks for giving **{zellkonverter}** a go. Firstly, just for clarification, the `.h5ad` file format doesn't have a concept of alternative experiments so this is one of the things...

Hi. From a quick internet search this looks this a C error. We don't directly use any C code in **{zellkonverter}** so it could be coming from another R package,...

Running `readH5AD()` inside a **conda** environment can sometimes be problematic. In that case using `AnnData2SCE()` can work better but you need to be somewhat familiar with **{reticulate}**/Python to try that....

I was able to load the file in Python but I ran out of memory trying to read it with **{zellkonverter}**. Maybe we are hitting the limits of what R...

Running **{zellkonverter}** in a Jupyter notebook can be sometimes problematic. It seems like for some reason R doesn't see `adata` as a Python object. Do you have **anndata2ri** installed? What...

I think this is because you haven't passed `adata` to your R chunk using the `--i` option. See the example in the best practices book https://www.sc-best-practices.org/introduction/interoperability.html#accessing-r-from-python.

If you have managed to get a `SingleCellExperiment` object then **{zellkonverter}** is no longer involved so this might be a better question for the **{DelayedArray}** maintainers. Do you see the...

Initially I got: ``` ValueError: Unknown dtype dtype('int64') cannot be converted to ?gRMatrix. ``` But if I change to: ```python mat = csr_matrix(poisson(1, size=(100, 2000)), dtype=numpy.float32) ``` Then both of...
