Figure 4.

The mean of the absolute projected amplitudes corresponding to each basis shape from NMF is taken for individual worms of four different genotypes. (wild type N2: n = 1303, snf-6: n = 43, nlp-1: n = 22, egg-5: n = 23) snf-6 and nlp-1 worms have significantly increased head motion, but normal movement in the rest of their body in terms of magnitude (p_adj(snf-6) = 3.13 × 10⁻¹⁴, p_adj(nlp-1) = 6.83 × 10⁻⁴), while the opposite can be observed in egg-5 mutants (p_adj(hip) = 8.19 × 10⁻⁵, p_adj(tail) = 2.48 × 10⁻⁶). ***Indicates p < 0.001.
