The delta scans between MS/MS clusters are shown above. Left, two datasets from day 1 and day 20 from the anaerobic microbial community extracted from cow rumen fluid were clustered using the MS/MS spectral clustering algorithm. Each point represents a spectral cluster. Right, spectral clustering was performed using two datasets from the same sample day. The spectral clustering method shows a significant difference in community structure between sample days one and five (i.e., days 1 and 20).
