FASTA Sequence Length Extractor

FASTA Sequence Length Extractor

This Python script extracts sequences from a FASTA file based on a minimum length threshold. It uses the Biopython library for efficient handling of biological data.

Usage

1. Install the required dependencies:

   pip install biopython

2. Run the script:

   python Extract.py input.fasta output.fasta 500

   • input.fasta: Path to the input FASTA file.
   • output.fasta: Path to the output FASTA file where the extracted sequences will be saved.
   • 500: Minimum length threshold for sequences (adjust as needed).

Example

python Extract.py example.fasta output.fasta 500

##This will extract sequences with a length greater than or equal to 600 bp from example.fasta and save them to output.fasta.
Requirements

    Python 3.x
    Biopython library
