Are you struggling with the complexities of analyzing Oxford Nanopore Technologies (ONT) sequencing data? Look no further! In this article, we will introduce you to baseDmux, a versatile and efficient workflow that simplifies the basecalling and demultiplexing of ONT sequencing data. Whether you are a researcher, bioinformatician, or data scientist, baseDmux offers a comprehensive solution for your data analysis needs.

Introducing baseDmux

baseDmux is a Snakemake workflow designed specifically for basecalling and demultiplexing ONT sequencing data. It utilizes a combination of tools, including Guppy, Deepbinner, MinIONQC, Multiqc, Porechop, and Filtlong, to provide a seamless and streamlined workflow. With baseDmux, you can perform basecalling, demultiplexing, quality control analysis, reads aggregation, trimming, filtering, and more, all in one intuitive workflow.

Key Features and Functionalities

baseDmux offers a wide range of features and functionalities to facilitate ONT sequencing data analysis:

  1. Guppy Basecalling: Perform basecalling using Guppy, with the ability to filter reads and subset fast5 reads based on a passed reads list.

  2. Guppy Demultiplexing: Demultiplex your fastq reads using Guppy and subset them into classified barcode folders based on barcoding summary information.

  3. Fast5 Conversion: Convert multi-read fast5 files to single-read fast5 files, preparing them for deepbinner analysis.

  4. Deepbinner Classification: Utilize Deepbinner to classify single-read fast5 files and generate classification output files.

  5. Deepbinner Bin: Classify your fastq files based on the classification output files, making it easy to subset fastq reads into barcode folders.

  6. MinIONQC and Multiqc: Perform quality control analysis using MinIONQC for each sequencing run, and utilize Multiqc to aggregate MinIONQC results across all runs.

  7. Demultiplex Report: Compare demultiplexing results from different runs and demultiplexers using multiqc_minionqc.txt information.

  8. Reads per Genome: Combine and concatenate fast5 and fastq barcodes for individual genomes based on demultiplexer information, facilitating further genome assembly and analysis.

  9. Porechop (Optional): Identify and remove adapters from reads using Porechop.

  10. Filtlong (Optional): Filter reads based on length and quality using Filtlong, with the ability to run multiple filtlong instances simultaneously.
