Dense body spacing along striations.

Age	Predominant Dense Body Spacing†
	Wild Type	fhod-1(ΔFH2)
L1	0.73 μm, n/a‡	n/a‡, n/a‡
L4	1.17 μm, 1.45 μm	n/a‡, n/a‡
Day 1 Adult	1.50 μm, 2.38 μm	n/a‡, 2.00 μm
Day 3 Adult	1.58 μm, 2.09 μm	3.74 μm, n/a‡
Day 4 Adult	1.84 μm, 2.25 μm	2.64 μm, n/a‡

^†Values shown are calculated as the inverse of the primary frequency (μm⁻¹) determined by FFT analysis of ATN-1::mCH fluorescence along striations (Figs S1, S2). Values from each of two trials are shown, determined from fluorescence profiles of all dense body-containing striations of two muscle cells (for L1 larvae) or eight dense body-containing striations in one muscle cell (for other ages) in each of ten animals per strain per developmental stage.

^‡No primary frequency was present, or the calculated predominant dense body spacing spanned multiple dense bodies.
