File Format: Signatures (Data)

A signature data file consists of signatures as rows, with the first column the signature name and the subsequent columns the mutation category probabilities.

Mutation categories are ordered according to the output of the corresponding category_list function in https://github.com/lrgr/mutation-signatures-data/blob/master/mutations/categories.py

For example, the signature data file for COSMIC signatures (mutation categorization SBS_96) begins

Signature	A[C>A]A	A[C>A]C	...
1	0.01109833	0.00914934	...
2	0.00068271	0.00061911	...
