Write fasta files from MCL results.

Given the output from the mcl clustering algorthim and a concatenated fasta file including all sequences used for clustering, outputs one fasta file per cluster including the sequences in that cluster.

write_fasta_files_from_mcl(path_to_ys = pkgconfig::get_config("baitfindR::path_to_ys"),
  all_fasta, mcl_outfile, minimal_taxa = 4, outdir, overwrite = FALSE,
  get_hash = TRUE, echo = pkgconfig::get_config("baitfindR::echo",
  fallback = FALSE), ...)

Arguments

path_to_ys	Character vector of length one; the path to the folder containing Y&S python scripts, e.g., "/Users/me/apps/phylogenomic_dataset_construction/"
all_fasta	Character vector of length one; the path to the fasta file including all query sequences concatenated together, i.e., the fasta file used to create the "all-by-all" blast database.
mcl_outfile	Character vector of length one; the path to the output from running mcl on blast distances.
minimal_taxa	Numeric; minimal number of taxa required to be present for the cluster to be written. Default 4, the minimum number of taxa needed for an un-rooted tree.
outdir	Character vector of length one; the path to the folder where the clusters should be written.
overwrite	Logical; should previous output of this command be erased so new output can be written? Once erased it cannot be restored, so use with caution!
get_hash	Logical; should the 32-byte MD5 hash be computed for all clusters concatenated together? Used for by drake_plan for tracking during workflows. If TRUE, this function will return the hash.
echo	Logical; should the standard output and error be printed to the screen?
...	Other arguments. Not used by this function, but meant to be used by drake_plan for tracking during workflows.

Value

One fasta file per cluster (cluster1.fa, cluster2.fa, etc.) will be written to outdir. If get_hash is TRUE, the 32-byte MD5 hash be computed for all .fa files concatenated together will be returned.
