(a) Coefficient of variation for C57Bl6 mouse movement arising from videos of indicated length, relative to a master 6-minute video. (b) Individual mouse movement per minute segment of master video. (c) Movement of C57Bl6 mice analysed in home cage (‘standard’) or a clean ‘empty’ transport box (see Fig. 2g for examples), using 2-minute videos. (d) Daily variation in movement of individual control NOD/SCID-GAMMA mice, filmed biweekly for 2 minutes each session, organised by increasing mouse activity. (e) Overall C57Bl6 mouse movement and (f) percentage of time spent in centre of cage using initially a control standard filming stage, followed by introduction of a translucent red house, and following manual handling and scruff. Statistics: (c) Welch’s two-sample unpaired t-test; (d–f) One-way ANOVA with Tukey multiple comparisons, ns: not significant; *p < 0.05; **p < 0.01; ***p < 0.001.
