MetaFlux is a lightweight, dependency-free genome-scale metabolic network analysis engine implemented entirely in Python using only NumPy and SciPy. It provides Flux Balance Analysis (FBA), Flux Variability Analysis (FVA), single-gene knockout screens, pairwise synthetic lethality detection, and 13C Metabolic Flux Analysis (13C-MFA).
We present GRNDynamics, a comprehensive gene regulatory network (GRN) simulation engine that unifies three complementary modeling frameworks under a single CPU-based pipeline: (1) Boolean network dynamics with exhaustive attractor enumeration for N ≤ 22 genes, (2) continuous ODE dynamics using Hill-function-based regulatory logic with adaptive Runge-Kutta integration, and (3) network inference from gene expression data using ARACNE and GENIE3. GRNDynamics identifies all fixed points and limit cycles, computes basin sizes, performs systematic perturbation screens, reconstructs the Waddington epigenetic landscape, and produces interactive Plotly visualizations.
Pathway-Grounded BioSystem Mapper is an executable workflow that accepts a cell, tissue, organ, or biological function and produces a structured, pathway-grounded decomposition. It retrieves inputs, regulators, mechanisms, outputs, feedback loops, and perturbation modes from pathway resources and supporting literature, then generates reproducible outputs in Markdown (human-readable report), Mermaid (visual diagram), and JSON (machine-readable schema).
