(a) Live-cell tumor ecosystem reconstituted ex vivo (Nguyen et al., 2018) using the tumor-on-chip technology (‘Materials and methods’). (b) CausalXtract’s live-cell image feature extraction module …
Example of time series of cellular features extracted by CausalXtract’s feature extraction module (CellHunter+) from the tumor ecosystems analyzed in this study (Figure 1a). It includes two …
(a) The signature of Granger–Schreiber temporal causality is a vanishing Transfer Entropy, that is, (‘Materials and methods’). In the time-unfolded causal network framework, it implies (i) the …
(a) Example of a 15-node causal network to generate benchmark time-series datasets based on linear combinations of contributions (Appendix 1). Examples of temporal causal networks reconstructed by …
(a) Example of a temporal causal network model () with a low-frequency periodic input () applied to X8 and a time-linear trend applied to X13. Corresponding temporal causal networks inferred by …
(a) Example of a 15-node causal network to generate more complex benchmark time-series datasets based on nonlinear combinations of contributions (Appendix 2). Examples of temporal causal networks …
(a) Summary causal network inferred by CausalXtract. The underlying time-unfolded causal network is shown in Figure 3—figure supplement 1. Red (resp. blue) edges correspond to positive (resp. …
(a) Time-unfolded causal network assuming stationary dynamics of cellular ecosystems implying translational time invariance of the inferred causal network. (b) Only edges involving at least one …
