an object of dagPeptides, output of fetchSequence or formatSequence
bg
could be "wholeGenome", "inputSet" or "nonInputSet"
model
could be "any" or "anchored"
targetPosition
could be "any", "Nterminus" or "Cterminus"
uniqueSeq
should the background sequence be unique?
permutationSize
how many times should it samples
rand.seed
random seed
replacement
Should sampling be with replacement?
proteome
an object of Proteome, output of prepareProteome
Details
The background could be generated from wholeGenome, inputSet or nonInputSet.
whole genome: randomly select subsequences from the whole genome with each subsequence
containing amino acids with same width of input sequences.
anchored whole genome: randomly select subsequences from the whole genome with
each subsequence containing amino acids with same width of input sequences
where the middle amino acids must contain anchor amino acid, e.g., K, which is
specified by user.
input set: same to whole genome, but only use protein sequence from input id and not
including the site specified in input sequences
anchored input set: same to anchored whole genome, but only use protein sequences from input id,
and not including the site specified in input sequences.
non-input set: whole genome - input set.
anchored non-input set: whole genome - input set and the middle amino acids must contain anchor amino acid.
Value
an object of dagBackground which contains background and permutationSize.
