Barcrawl Bartab

Barcrawl Bartab generates barcoded PCR primers and deconvolutes multiplexed high-throughput sequencing datasets to enable accurate sample attribution in genomic and metagenomic studies.

Key Features:

• Barcode-Primed Primer Design: Automates design of PCR primers integrated with unique barcode sequences for sample indexing in multiplexed sequencing experiments.
• Error Robustness and Uniqueness: Incorporates strategies to ensure barcode sequence uniqueness and robustness to sequencing errors to minimize misassignment and PCR-related biases.
• Deconvolution of Sequencing Data: Bartab deconvolutes multiplexed DNA sequence datasets to assign reads back to their originating samples.
• Validation with rRNA Primers: Includes a proof-of-concept validation using barcoded rRNA primers to demonstrate practical application in real-world datasets.

Scientific Applications:

• Metagenomic community profiling: Enables multiplexed sequencing of diverse microbial communities using barcoded primers for sample discrimination.
• High-throughput multiplexing: Supports simultaneous processing and sequencing of multiple specimens to increase throughput and data resolution.
• PCR-based amplicon studies: Facilitates design and downstream assignment of barcoded PCR amplicons, including rRNA-targeted assays.

Methodology:

Automated primer design integrates barcode sequences while enforcing uniqueness and resilience to sequencing errors; bartab applies deconvolution algorithms to parse complex multiplexed sequencing datasets and assign reads to samples.
