IFACE Surface Comparison
Compare two protein structures through their geometric and chemical surfaces.
Overview
Generates molecular surfaces from two protein structures and compares them with IFACE, jointly measuring intrinsic geometry, curvature, electrostatics, hydrogen-bonding propensity, and hydrophobicity while producing an interpretable soft vertex correspondence.

Features
- Generates molecular surfaces and physicochemical fields directly from uploaded protein structures.
- Computes the IFACE joint geometric-chemical distance between the generated surfaces.
- Reports separate geometry, chemical, and per-feature distance components.
- Produces a soft vertex-to-vertex correspondence matrix and the two strongest query matches for each reference vertex.
- Uses the documented approximately 1,000-vertex rapid-screening resolution.
Statistics
Neurosnap periodically calculates runtime statistics based on job execution data. These estimates provide a general guideline for how long your job may take, but actual runtimes can vary significantly depending on factors like input size or settings used.
