LSL-SFB Genome Assembly Pipeline Scripts

This directory contains the complete workflow scripts for assembling and annotating the LSL-SFB (chicken Segmented Filamentous Bacteria) genome.

Workflow Overview

The pipeline consists of 7 main steps:

  1. BWA Alignment - Align HiC reads to chicken genome + turkey SFB reference
  2. Extract SFB Reads - Extract reads mapping to turkey SFB contigs
  3. Generate Consensus - Create consensus sequence using samtools
  4. POLCA Polishing - Polish consensus with POLCA
  5. HiC Scaffolding - Scaffold with Juicer and 3D-DNA
  6. Prokka Annotation - Annotate genome with Prokka
  7. Quality Assessment - Assess quality with BUSCO and CheckM

Software Requirements

  • BWA v0.7.17
  • SAMtools v1.19.1
  • MaSuRCA (for POLCA)
  • Juicer v1.5.7
  • 3D-DNA v180114
  • JuiceBox v1.11 (for manual curation)
  • Prokka v1.14.6
  • BUSCO v5.x
  • CheckM
