Read h5ad scanpy

scanpy.read(filename, backed=None, sheet=None, ext=None, delimiter=None, first_column_names=False, backup_url=None, cache=False, cache_compression=Empty.token, **kwargs) Read file and return AnnData object. To speed up reading, consider passing cache=True, which creates an hdf5 cache file. Parameters filename : Union [ Path, str] anndata for R. anndata is a commonly used Python package for keeping track of data and learned annotations, and can be used to read from and write to the h5ad file format. It is also the main data format used in the scanpy python package (Wolf, Angerer, and Theis 2018). However, using scanpy/anndata in R can be a major hassle.

Alternatively, download the whole scanpy-tutorial repository. Note In Jupyter notebooks and lab, you can see the documentation for a python function by hitting SHIFT + TAB. Hit it twice to expand the view. [2]:First, let Scanpy calculate some general qc-stats for genes and cells with the function sc.pp.calculate_qc_metrics, similar to calculateQCmetrics in Scater. It can also calculate proportion of counts for specific gene populations, so first we need to define which genes are mitochondrial, ribosomal and hemoglogin. For our example, we’ll read the PBMC3k data files using the read_10x_mtx() function from Python’s scanpy package, then writing the data to file in .h5ad format. We’ll access scanpy using the reticulate R package. If you have difficulty accessing scanpy in this section,please see. This contributed tutorial shows how to use cell2location ...
