TC to TT ratio at the predicted damage sites retrieved from Damage-seq and XR-seq data sets of two replicates

Method	0 m (5 m*)	20 m	1 h	2 h	4 h
Damage-seq rep 1	0.88	0.82	0.61	0.69	0.46
Damage-seq rep 2	0.98	0.86	0.78	0.67	0.49
XR-seq rep 1	1.88	1.94	2.18	2.06	1.71
XR-seq rep 2	2.05	1.79	1.92	2.00	1.61

*Initial time point for XR-seq was 5 min after irradiation, whereas it was 0 min for Damage-seq. Rep, replicate.
