BSA on calcium data

Cell	BSA Period ± σ (s)	BSA-NS Period ± σ (s)
1	97.4 ± 0.23	97.3 ± 0.15
2	80.9 ± 0.63	75.2 ± 10.1
3	74.6 ± 0.19	74.6 ± 0.85
4	123.8 ± 0.16	124.2 ± 1.18
5	88.9 ± 0.22	123.9 ± 0.61
6	74.6 ± 0.21	113.7 ± 16.16
7	121.9 ± 0.22	146.1 ± 21.53
8	74.4 ± 0.92	75.2 ± 2.69
9	48.2 ± 0.3	64.5 ± 13.94

Analysed calcium oscillations in M. truncatula root hair cells in response to bacterial symbionts. The BSA shows strong underlying signals in the data, but the cell-to-cell variability is high. BSA and the BSA-NS disagree when there are multiple peaks present, as can be seen by the large standard deviation, σ, of the BSA-NS average period estimate.
