Assign taxonomy

This directory is to assign taxonomy to your list of ASVs inferred from each study, using the Silva reference database. It allows to assign taxonomy on a computer cluster instead of running it on your local computer.

Necessary elements:

  1. Fasta files containing the Silva reference database must be put in the silva-taxonomic-ref/ subdirectory (see README file in the silva-taxonomic-ref subdirectory)
  2. Input ASV tables in the input/ subdirectory with samples as rows and ASV sequences in column names. These input ASV tables should have no chimera and are generated by the scripts 01_Dada2-NameDataset.Rmd in each individual dataset subdirectory of analysis-individual
  3. R script to assign taxonomy on all datasets present in the input/ subdirectory => Rscript_assignTaxonomy_cluster.R is already provided in this directory, but make sure to change the file paths at the top of the R script!!
  4. Bash script to execute the R script on your computer cluster (recommended to provide at least XXXXX of virtual memory!). Make sure to modify the bash script provided in this directory to fit your cluster.
