SDSE

SDSE simulates DNA sequence evolution under a general stochastic nucleotide-substitution model for evolutionary and phylogenetic analyses.

Key Features:

• General stochastic model: Implements a general stochastic process for DNA sequence evolution that encompasses previously established nucleotide substitution schemes.
• Finite, variable-length sequences: Handles finite DNA sequences of variable lengths.
• Substitution event simulation: Simulates nucleotide substitution events over time according to specified substitution rates.
• Customizable parameters: Supports user-defined parameters to tailor substitution rates and model settings.
• GenBank compatibility: Reads and writes sequence data in the GenBank file format.

Scientific Applications:

• Evolutionary biology research: Enables testing of molecular evolution hypotheses by simulating sequence evolution under varied substitution models.
• Comparative genomics: Generates simulated sequences that mimic evolutionary processes for comparative genomic analyses.
• Phylogenetic analysis: Produces model-based sequence data for assessing phylogenetic reconstruction methods and evolutionary relationships.

Methodology:

Applies a stochastic process to DNA sequences, simulating substitution events over time according to predefined or user-specified substitution rates that reflect various nucleotide substitution schemes, operates on finite variable-length sequences, and uses GenBank-formatted sequence files.
