StructuralGT Software
COMPASS develops an open-source package for the graph theoretic analysis of networked materials called StructuralGT. StructuralGT can operate on any images of networked materials, and has already been used to produce results on microscopy (confocal, atomic force, transmission electron, scanning electron) and macroscale videography in 2D, as well as 3D electron tomography.

Examples of StructuralGT
StructuralGT has been used for many pieces of research. Here are a few of our favorite examples.
Fast and Massive Production of Aramid Nanofibers via Molecule Intercalation
Cumulative spider plot of graph theoretical parameters of three different ANF aerogels prepared using traditional mechanical nanofibrillation with DMSO + KOH (left), nanofibrillation in DMSO + KOH + H2O (center), and molecule intercalation in DMSO + KOH + IPA (right) with significant structural differences being shown in the molecule-intercalated network.
Graph–Property Relationships for Complex Chiral Nanodendrimers

Autocatalytic Nucleation and Self-Assembly of Inorganic Nanoparticles into Complex Biosimilar Networks
Comparative evaluation of biosimilarity of inorganic self-replicating nanoparticle (SR NP, left), bacterial (Streptococcus spp. on agar, center), and fungal (R. stolonifera on Capsicum annuum L, right) networks showing the NP networks are structurally identical to those produced by Streptococcus spp.

ResponseGT Software
ResponseGT is a software package to quickly and easily compute linear response on physical networks (circuits, transport networks, spring-mass networks, etc.). It takes as input the physical parameters of the components of a network, including edge “admittance,” (such as conductivity or stiffness) and vertex “inertia” or other connections to a background medium (these are shown in first figure). Users can then impose different boundary conditions to this network, such as an imposed electric potential (left-right in the second figure, edge color represents edge current, increasing from blue to red), mechanical shear (on the top/bottom of the third figure, edge color represents positive/negative tension, magnitude proportional to thickness), or internal constraints, like the condensed nodes in the shaded circle of the third figure.
