Functions in primerTree (1.0.6)

calc_rank_dist_ave

Summarize pairwise differences.

identify.primerTree_plot

identify the point closest to the mouse click only works on single ranks

filter_seqs

Filter out sequences retrieved by search_primer_pair() that are either too short or too long. The alignment and tree will be recalculated after removing unwanted reads.

get_taxonomy

Retrieve the taxonomy information from NCBI for a set of nucleotide gis.

clustalo

Multiple sequence alignment with clustal omega

layout_tree_ape

layout a tree using ape, return an object to be plotted by plot_tree

accession2taxid

Maps a nucleotide database accession to a taxonomy database taxId

get_sequence

Retrieves a fasta sequence from NCBI nucleotide database.

get_sequences

Retrieves fasta sequences from NCBI nucleotide database.

bryophytes_trnL

PrimerTree results for the bryophyte trnL primers

plot.primerTree

plot function for a primerTree object, calls plot_tree_ranks

primerTree

primerTree Visually Assessing the Specificity and Informativeness of Primer Pairs

plot_tree_ranks

plots a tree along with a series of taxonomic ranks

plot_tree

plots a tree, optionally with colored and labeled points by taxonomic rank

parse_primer_hits

Parse the primer hits

tree_from_alignment

Construct a neighbor joining tree from a dna alignment

mammals_16S

PrimerTree results for the mammalian 16S primers

summary.primerTree

Summarize a primerTree result, printing quantiles of sequence length and pairwise differences.

seq_lengths.primerTree

Method for primerTree objects

seq_lengths

Get a summary of sequence lengths from a primerTree object

search_primer_pair

Automatic primer searching Search a given primer pair, retrieving the alignment results, their product sequences, the taxonomic information for the sequences, a multiple alignment of the products

primer_search

Query a pair of primers using ncbi's Primer-BLAST, if primers contain iupac
