quality.filter | R Documentation |
This function takes an LTRpred
output table as input
and eliminates false positive predictions.
quality.filter(pred, sim, n.orfs, strategy = "default")
pred |
|
sim |
LTR similarity threshold. Only putative LTR transposons that fulfill this LTR similarity threshold will be retained. |
n.orfs |
minimum number of ORFs detected in the putative LTR transposon. |
strategy |
quality filter strategy. Options are
|
Quality Control
ltr.similarity
: Minimum similarity between LTRs. All TEs not matching this
criteria are discarded.
n.orfs
: minimum number of Open Reading Frames that must be found between the
LTRs. All TEs not matching this criteria are discarded.
PBS or Protein Match
: elements must either have a predicted Primer Binding
Site or a protein match of at least one protein (Gag, Pol, Rve, ...) between their LTRs. All TEs not matching this criteria are discarded.
The relative number of N's (= nucleotide not known) in TE <= 0.1. The relative number of N's is computed as follows: absolute number of N's in TE / width of TE.
