trisicell.ul.to_tree
- trisicell.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.
