ano-spp

A targeted amplicon sequencing panel to simultaneously identify mosquito species and Plasmodium presence across the entire Anopheles genus

Repository structure

  • data - annotation tables for 62 mosquito and 2 Plasmodium amplicons
  • pipeline_dada2 - sequencing data processing and QC pipeline based on DADA2
  • pipeline_seekdeep - sequencing data processing and QC pipeline based on SeekDeep
  • tracking - sample manifests for pipelines grouped by Illumina MiSeq run with short descriptions of sample sets
  • work - analyses code and data files; each step has an associated conda environment file env.yml listing the dependencies

Analysis outline

  • 1_panel_design - search for potential amplicon sites in the 21 Anopheles genomes alignment and annotation of the final amplicon set
  • 2_plasmodium_rebalancing - search for Plasmodium primer concentrations optimal for parasite detection
  • 3_plasmodium_qpcr - comparison of amplicon sequencing and qPCR for Plasmodium detection
  • 4_ref_extraction - amplicon sequence extraction from reference genomes (supplementary step)
  • 5_synteny_plot - plotting amplicon positions in three mosquito species genomes
  • 6_ag1k_extraction - amplicon sequence extraction from Ag1000g Phase 2 haplotypes and within-species distances estimation (supplementary step)
  • 7_species_id - multiple species dataset exploration, clustering-based species ID, species tree
  • 8_ag1k_analysis - Ag1000g population structure and diversity based on amplicon sequences
  • 9_coi_its - COI and ITS2 Sanger sequencing data analysis for species ID confirmation, within-species diversity estimates
