Supplementary material of Sabine C. Fischer, Simon Schardt, Joaquín Lilao-Garzón and Silvia Muñoz Descalzo "The salt-and-pepper pattern in mouse blastocysts is compatible with signalling beyond the nearest neighbours." This folder contains the preprocessing steps for the rule-based and ODE-based models. In particular, it contains - "DataFromPython" with the results from the simulations in Python of the signalling models (Schardt & Fischer, arXiv, 2022) - "TissueFeatures" with the processed data in Mathematica's .mx format - "Results" with the output from the preprocessing steps. In particular, the files *Comp.mx contain all the information for the neighbourhood analyses. All other code concerning the analyses is available on github: https://github.com/scfischer/fischer-et-al-2023
