+### **4.1 Normalization and HVG Selection**
`Panpipes` offers two different normalization and HVG selection flavours, `'seurat'` and `'squidpy'`.
The `'seurat'` flavour first selects HVGs on the raw counts using analytic Pearson residuals, i.e. [scanpy.experimental.pp.highly_variable_genes](https://scanpy.readthedocs.io/en/stable/generated/scanpy.experimental.pp.highly_variable_genes.html). Afterwards, analytic Pearson residual normalization is applied, i.e. [scanpy.experimental.pp.normalize_pearson_residuals](https://scanpy.readthedocs.io/en/stable/generated/scanpy.experimental.pp.normalize_pearson_residuals.html). Parameters of both functions can be specified by the user in the yaml file.
The `'squidpy'` flavour runs the basic scanpy normalization and HVG selection functions, i.e. [scanpy.pp.normalize_total](https://scanpy.readthedocs.io/en/stable/generated/scanpy.pp.normalize_total.html), [scanpy.pp.log1p](https://scanpy.readthedocs.io/en/stable/generated/scanpy.pp.log1p.html), and [scanpy.pp.highly_variable_genes](https://scanpy.readthedocs.io/en/stable/generated/scanpy.pp.highly_variable_genes.html).
