Two computer programs for rapid entry of DNA sequence data

Area of Science:

• Bioinformatics
• Computational Biology
• Molecular Biology

Background:

• Accurate DNA sequence data entry is crucial for genetic analysis and downstream bioinformatics applications.
• Manual data entry can be time-consuming and prone to errors, impacting research efficiency.
• Existing DNA sequence manipulation programs require compatible data formats.

Purpose of the Study:

• To develop and describe two novel computer programs for efficient and accurate DNA sequence data entry.
• To provide tools that generate data files compatible with established bioinformatics software.
• To reduce errors and save time in the DNA sequencing workflow.

Main Methods:

• DIGISEQ: Utilizes a sonic digitizer for semi-automated sequence entry by tracing gel bands, with algorithms correcting for lane variations.
• TYPESEQ: Employs a reconfigured keyboard layout for rapid nucleotide and ambiguity code input, guided by user-defined gel lane order.
• Both programs incorporate auditory feedback (tones) for each nucleotide and ambiguity code entered, verifying input accuracy.

Main Results:

• DIGISEQ offers efficient and accurate semi-automated DNA sequence entry, minimizing the need for re-entry due to lane variations.
• TYPESEQ provides a keyboard-based method for rapid and accurate data input, enhancing user efficiency.
• Both programs generate DNA sequence files directly usable by popular bioinformatics tools like R. Staden's DataBase system, UW Genetics Computer Group, DNASTAR, and D. Mount.

Conclusions:

• DIGISEQ and TYPESEQ significantly improve the speed and accuracy of DNA sequence data entry.
• These programs enhance the usability of DNA sequence data by ensuring compatibility with major bioinformatics platforms.
• The auditory feedback mechanism in both programs effectively reduces input errors and the need for visual screen verification.
