Table 1. Summary of number of steps detected from 100 realizations of the simulated traces.

	Min.	1st Qu.	Median	Mean	3rd Qu.	Max.
(a) GLS	23.00	33.00	35.00	33.79	36.00	40.00
(b) Ignoringcorrelation	45.00	56.00	63.50	65.64	75.00	91.00
(c) True Gaussian	26.00	28.00	30.00	29.75	31.00	36.00
(d) KERS	4.00	4.00	4.00	4.74	5.00	8.00

Four different procedures were used to detect steps, where Procedure (a), (b) and (d) are for traces with correlated noise analyzed with GLS method (a), ignoring noise correlation and assuming Gaussian noise (b) and the KERS method (d); Procedure (c) was done for traces with Gaussian white noise that were analyzed using the GLS method.
