Data collection and preprocessing
Background signal level was derived from the values for that feature among placebos, as the placebo mean plus one standard deviation .
Data collection and preprocessing
Finally, the vaccinee values for the feature were scaled and centered to a mean of 0 and a standard deviation of 1, with values truncated to 60.
Supervised learning: Classification
Nonetheless, even with a rigorous 200-replicate fivefold cross-validation, a mean AUC of 0.83 ( standard deviation of 0.10) was observed, indicating that antibody features are highly and robustly predictive of high vs. low ADCP activity.
Supervised learning: Classification
Despite the reduction in data considered, Fig 3C and 3D shows that the resulting performance with the filtered feature set is comparable to that with the complete feature set, with a mean AUC of 0.84 ( standard deviation 0.10).
Supervised learning: Classification
We found that on average an AUC of 0.79 was obtained, with a range from 0.67 to 0.87 and a standard deviation of 0.04 (recall that the PCC-based approach obtained 0.84).
Supervised learning: Regression
The models are clearly predictive of ADCP, obtaining a mean Pearson correlation coefficient PCC = 0.64 ( standard deviation 0.15) over the 200-replicate fivefold.
Supervised learning: Regression
Models learned from the filtered features from Fig 2B maintain about the same accuracy (mean PCC = 0.61 with standard deviation 0.15 for the 200-replicate fivefold (Fig 4D); an example LOOCV scatterplot is illustrated in Fig 4C).
Supervised learning: Regression
Similarly, PCA-based models attain mean PCC of 0.61 With standard deviation 0.15 (Fig 4E and 4F), based largely on PC2 (1gG2/4 vs. 1/3) and someWhat on PCS (IgG4 vs. others), as can be seen in Fig 41.

Intervention target validation
For our test cases, we find that using 10,000 time steps for each evolution stage (with and then without prescribed node states) is enough to preserve the first three digits of the estimated probabilities p Am of reaching the attractor of interest, consistent with what is expected from the standard deviation of the estimated probability p Am.
Intervention target validation
For our test cases, we find that 100,000 initial conditions are enough to estimate the probabilities p Am of reaching the attractor of interest with an error ( standard deviation of the estimated probability p Am) of 3' 10'3 [p Attr(1—p Attr)] 1/ 2.
Intervention target validation
The number of time steps we use is enough to show no changes in p Am beyond what is expected from the standard deviation of the estimated probability p Am, and is also found to be enough for the initial conditions to reach the attractors when no interventions are applied.

Definition of kinetic signatures
Bayesian evidence values and model parameter estimates (and their standard deviations ) are computed using nested sampling for all signatures for each time series.
Definition of kinetic signatures
CAGE clusters are assigned to one of the exponential kinetic signatures if log Z for that signature is greater than 10 times log Z for the linear model and log Z minus its standard deviation (sd) is greater than log Z plus the estimated sd for any other eXponential signature (nested sampling computes log Z for parameters mapped to O..1 and we used the resulting log Z for the unit cube for model comparison).
Results
A cluster was assigned to a ‘no decision’ category if the values of log Z (and the associated standard deviations ) computed for each model did not permit a clear assignment.

Coupled Stuart-Landau/Kuramoto model parameters
For both models, the natural frequencies of the oscillators in our simulation are given as a Gaussian distribution to simulate alpha with mean at 10 Hz and standard deviation 1, making wj around 10211 rad/ s. Time delay is (a) given an identical value between 2ms and 50 ms for all edges (for model networks as well as Gong et al.’s and Hagmann et al.’s human brain networks), or (b) given proportional to the physical distances for each edges with propagation speed of between 5 to 10m/ s (for Gong et al.’s human brain network) [60, 61].

Identification of mathematical relationships among node degree, amplitude of local oscillations and directionality of interactions
Fig 2A shows the mean phase coherence (measure of how synchronized the oscillators are; see Materials and Methods for details) [42] for two groups of nodes in the network: 1) hub nodes, here defined as nodes with a degree above the group standard deviation (green triangles, 8 out of 78 nodes); and 2) peripheral nodes, here defined as nodes with a degree of 1 (yellow circles, 33 out of 78 nodes).
Supporting Information
Each plot shows distinct local dynamics for hub nodes (darker green diamond: defined as nodes With degree above the group standard deviation), and peripheral nodes (lighter green square: defined as nodes With degree 1 for scale-free network, and as nodes With degree below the group standard deviation for other networks) as coupling strength S is varied.
Supporting Information
Nodes are indexed in decreasing order of their degree; the degree distribution graph is red if the node degree is less than the average degree of the network, green if it is more than the average, and blue if it is higher than one standard deviation from the average.

Microarray metadataset
To prevent the need to recalculate the null distribution for every pattern of NAs in the data for empirical ITK_CYCLE (there were 5005 unique NA permutations in the data), the NAs were replaced by random noise drawn from a Gaussian distribution with mean and standard deviation that match those of the data on the whole.
