Our hydrogel provides a new approach to study biological small-scale attachment mechanisms in-vivo. This repository contains the indentation data of different hydrogels that we tested and the post processing to fit a Maxwell model and reconstruct the effective Young's modulus and relaxation time constant. Furthermore we include a blender shader to convert the global height of a mesh into intensity in a rendering, as well as a script to eliminate large scale deformations. This was used to flatten OCT data to reconstruct local changes in height and thus measure deformation in imprints. The script for that is also included. Finally we provide the surface renderings of all OCT scans (both ex vivo and in vivo) as well as the script to estimate forces from these imprints using the relationships presented in the paper. For further information see the readme file inside the repository.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[{"awardTitle":"NWO
