scphylo.ul.to_tree#
- scphylo.ul.to_tree(df)[source]#
Convert a conflict-free matrix to a tree object.
This function converts a conflict-free matrix to a tree object in which nodes are labled with cells and edges are lables with mutations. The root is labled by ‘root’. Mutations are seperated by .graph[‘splitter_mut’] and cells are seperated by .graph[‘splitter_cell’]. Those mutations that are not present in any cell are stored in .graph[‘become_germline’]. Mutations happed once during the evolution so there is no repetitive mutation.
- Parameters
df¶ (
pandas.DataFrame) – A genotype dataframe in which rows are cells and columns are mutations. Note that this dataframe must be conflict-free.- Returns
A perfect phylogenetic tree.
- Return type
