Table 1. Ensemble selection results.

	Experimental		Ensemble*
	RDC†	FRET	RDC†	FRET	Q factor‡
Twitch-2B	4.29	0.78	5.60	0.79	0.31
Twitch-6	11.43	0.90	9.29	0.88	0.07

*Results from the best-fitting ensembles of six structures selected with the protocol in Materials and Methods.

†RDCs shown are the distribution ranges of the experimental and ensemble parameters. The experimental (ensemble) RDC ranges from −2.01 to 2.27 Hz (−2.50 to +3.10 Hz) for Twitch-2B and from −3.48 to +7.95 Hz (−2.64 to +6.65 Hz) for Twitch-6.
