Table 1. Regime of selection as determined by SVM.

	Near-fixation regime	Postfixation regime
XP-SFselect and Sf windows	75	274
XP-SFselect-only windows	211	8

The number of genomic windows found significant under XP-SFselect (568 overall) with higher class probabilities for the near-fixation, or the post-fixation regime. Showing windows found only by XP-SFselect, as well those identified by both XP-SFselect and S_f. These results imply that while S_f is sensitive to the post-fixation regime, XP-SFselect captures both types of selection.
