Usage

writeFasta(file, ...)

Arguments

file	where to write

library(seqinr)
#library(prozor)
file = system.file("extdata/fgcz_contaminants2021_20210929.fasta.gz",package = "prozor")
fasta = readPeptideFasta(file = file)
revfasta <- reverseSeq(fasta)
decoyDB <- c(fasta,revfasta)
stopifnot(length(decoyDB) == 2 * length(fasta))
## Not run:
