btwisted

btwisted calculates the helical twist of B-DNA sequences to quantify DNA twisting and related structural properties.

Key Features:

• EMBOSS integration: Operates as a component of the EMBOSS suite, enabling programmatic interoperability with other EMBOSS applications.
• EMBOSS C libraries: Implements computations using the extensible C programming libraries provided by EMBOSS for robustness and performance.
• ACD-based configuration: Supports customization via Application Configuration Description (ACD) files to modify parameters and behavior without source code changes.
• API conformity: Follows EMBOSS API programming guidelines to structure application logic and data handling.

Scientific Applications:

• DNA structural analysis: Quantifies helical twist, supercoiling indicators, and torsional strain in B-DNA sequences.
• Genomics and regulation: Provides twist metrics relevant to replication, transcription, and genetic regulation studies.
• Structural biology and epigenetics: Informs investigations of DNA conformational properties that influence chromatin structure and epigenetic states.

Methodology:

Computational analysis of B-DNA sequences to determine the degree of twisting, implemented using EMBOSS C libraries and configurable via ACD files.
