SeqWiz

SeqWiz provides SQLite- and JSON-based sequence database formats and Python tools for proteomics database management and proteoform-aware sequence analysis.

Key Features:

• SQPD (SQLite-based Sequence Database): A local SQLite-based sequence database aligned with PEFF standards that enables efficient searches for complex proteoforms.
• SET (JSON-based Entry List): A JSON-based entry list format for creating optimized subsets of sequence data.
• Performance and Efficiency: SQPD and SET reduce time and resource consumption compared with FASTA and PEFF formats for large-scale proteomic analyses.
• Modularized Tools (Python): A collection of tools and modules implemented in Python to support database preparation and downstream sequence analyses.
• Functionalities: Supports species-specific database retrieval, format conversion, sequence generation, filtering, and sequence analysis while maintaining compatibility with FASTA and PEFF.

Scientific Applications:

• Proteoform-aware proteomics: Enables proteoform-focused searches and database management for precision proteomics studies.
• Database creation and renewal: Facilitates efficient construction and updating of large sequence databases for proteomic workflows.
• Integration and standardization: Supports PEFF-aligned formats and interoperability with FASTA/PEFF-based software ecosystems.
• Sequence-level investigation: Enables detailed exploration of protein sequence variations to inform studies of biological processes.

Methodology:

Implements an SQLite-based SQPD and JSON-based SET formats, performs species-specific database retrieval, format conversion, sequence generation, filtering, and proteoform-aware searches, and is implemented in Python.
