ReadH5AD and WriteH5AD will try to automatically fill slots based on data type and presence. For example, objects will be filled with scaled and normalized data if adata.X is a dense matrix and raw is present (when reading), or if the scale.data slot is filled (when writing). The following is a list of how objects will be filled. In addition ... WebOverview. This package provides a lightweight interface between the Bioconductor SingleCellExperiment data structure and the Python AnnData -based single-cell analysis environment. The idea is to enable users and developers to easily move data between these frameworks to construct a multi-language analysis pipeline across R/Bioconductor and …

Your H5AD files seems to have raw data as a dense matrix, which ReadH5AD currently does not support.
WebRNA Velocity#. As a powerful assessment of cell status, RNA velocity analyses expression dynamics based on scRNA-seq data, which generates the spliced and unspliced matrices in loom file, also called RNA abundance. WebIntegration with bulk RNA-seq data. #. A current limitation of single-cell datasets is the high cost, low sample size and often the lack of associated clinical information. On the other hand bulk RNA-seq experiments are comparatively cheap, and vast amounts of experimental data has accumulated in public repositories, including large-scale ...
