Facilitate the recognition of secondary structure patterns, including beta-sheet and alpha-helix domains.

Main Methods:

Developed as an object-oriented Python library.
Leverages MDAnalysis, PyTorch, and NetworkX for pattern recognition.
Interfaces with Pandas, Numpy, and Matplotlib for accessible data presentation.
Supports various file formats from popular simulation packages (NAMD, Gromacs, OpenMM).

Main Results:

Morphoscanner2.0 successfully performs structural and temporal analysis on MD simulation trajectories.
The library can identify and track the formation of beta-structured domains.
A routine for tracking alpha-helix domain formation is included.
Results are made accessible through standard data science libraries.
