SPLICE, a computer program for automated extraction of information from GenBank sequence entries

Area of Science:

• Bioinformatics
• Computational Biology
• Genomic Data Management

Background:

• GenBank tape format is a common but complex format for storing biological sequences.
• Extracting and assembling fragmented sequences from GenBank files can be challenging for downstream analysis.
• Existing tools may lack the flexibility to handle various fragmentation scenarios.

Purpose of the Study:

• To develop a software tool, SPLICE, for efficient sequence extraction and assembly from GenBank files.
• To enable the creation of unified sequence files suitable for standard bioinformatics analysis.
• To address the challenge of handling sequences split across multiple GenBank entries or files.

Main Methods:

• Developed SPLICE software utilizing GenBank file format analysis.
• Implemented algorithms to parse feature tables and extract relevant sequence data.
• Designed functionality to identify and splice together contiguous or discontiguous sequence fragments.
• Ensured compatibility with MS/DOS and Unix operating systems.

Main Results:

• SPLICE successfully extracts sequences from GenBank tape format.
• The software can analyze feature tables to reconstruct complete sequences.
• SPLICE effectively splices together sequences fragmented within a single file (e.g., peptides).
• It can also assemble sequences spanning multiple GenBank files (e.g., exons).
• SPLICE supports batch processing and can be integrated as a subprocess.

Conclusions:

• SPLICE provides a robust solution for sequence data extraction and assembly from GenBank.
• The tool enhances the usability of GenBank data for various sequence analysis applications.
• SPLICE offers flexibility and efficiency for researchers working with fragmented genomic information.
