=============================
Operations on AnnData objects
=============================

Performs the following operations:

* Change observation fields, mostly for downstreaming processes convenience. Multiple fields can be changed as one.
* Flag genes that start with a certain text: useful for flagging mitochondrial, spikes or other groups of genes.
* For the flags created, calculates qc metrics (pct_<flag>_counts).
* Calculates `n_genes`, `n_counts` for cells and `n_cells`, `n_counts` for genes.
* For top <N> genes specified, calculate qc metrics (pct_counts_in_top_<N>_genes).
* Copy from a set of compatible AnnData objects (same cells and genes):
  * Observations, such as clustering results.
  * Embeddings, such as tSNE or UMAPs.
  * Unstructure annotations, like gene markers.

This functionality will probably be added in the future to a larger package.
