MDsrv: visual sharing and analysis of molecular dynamics simulations.

Area of Science:

• Computational biology
• Biophysics
• Structural biology

Background:

• Molecular dynamics (MD) simulations provide atomic-level insights into macromolecular motion.
• Current tools often require local data access and advanced user skills.
• Interactive visualization and collaborative analysis are crucial for MD data interpretation.

Purpose of the Study:

• To enhance the MDsrv tool for simplified upload, sharing, and online analysis of MD trajectories.
• To improve the accessibility and applicability of MD trajectory visualization.
• To integrate basic analytical functions supporting visual analysis.

Main Methods:

• Web-based streaming of MD trajectories using the MDsrv.
• Implementation of simplified session creation for trajectory exchange with preset views.
• Integration of remote dataset access for trajectory visualization.
• Development of initial analysis modules (sequence/structure alignment, distance, RMSD).
• Utilizing Mol* for enhanced visualization performance.

Main Results:

• MDSrv now simplifies sharing and online analysis of MD trajectories.
• Remote data access significantly broadens the tool's applicability.
• Integrated analyses like sequence alignment and RMSD calculations support visual exploration.
