• To provide tools for display, animation, and time-series analysis of molecular trajectories.
• To enhance the efficiency of molecular modelers in handling large simulation outputs.

Main Methods:

• Development of the SCARECROW molecular graphics program.
• Implementation of a macro language for scripting animations and time-series analysis.
• Inclusion of extensive atom selection and coloring commands for focused analysis.
• Support for on-screen viewing and external transfer of time-series data.

Main Results:

• SCARECROW facilitates the analysis and display of large molecular dynamics data files.
• The program supports visualization, animation, and detailed analysis of molecular dynamics trajectories.
• Automated display and analysis of time series are achievable through scripting.
• Users can effectively focus on relevant molecular regions using advanced selection and coloring options.

Conclusions:

• SCARECROW is a valuable tool for molecular modelers working with complex molecular dynamics data.
• The program enhances the ability to analyze and visualize simulation results.
• Its scripting capabilities and advanced features streamline the process of molecular data interpretation.
