locus-class: Class "locus"

In heibl/megaptera: MEGAPhylogeny Techniques in R

Description

Class for genetic input parameters for megapteraProj.

Objects from the Class

Objects can be created by calls of the form locus(..., not, search.fields = c("gene", "title")).

Slots

kind

sql

a vector of mode character holding a SQL-compatible transformation of the first alias for naming database tables.

aliases

a vector of mode character giving strings that should be seached for; the first element is taken to name the corresponding postgreSQL tables.

not

a vector of mode character giving strings that should be excluded from the search results; corresponds to the use of NOT in GenBank query.

adj.gene1

adj.gene2

search.fields

a vector of mode character setting the search fields (or attributes) of the Nucleotide database to be searched for the strings specified via the ... argument.

use.genomes

logical, if TRUE sequences of loci will be extracted from annotated genomes of chloroplasts and mitochondria. Due to the existance of different annotation styles, which might (still) be incompatible with megaptera, this option can be used to turn the extraction of sequences from whole genomes off.

align.method

a character string giving the alignment method in MAFFT. Available accuracy-oriented methods for less than 200 sequences are "localpair", "globalpair", and "genafpair"; "retree 1" and "retree 2" are for speed-oriented alignment. The default is "auto", which lets MAFFT choose an opproriate alignment method.

min.identity

numeric between 0 and 1, giving the minimum proportion of nucleotides required to be identical with the reference sequence in order to be included in an alignment (default: 0.75)

min.coverage

numeric between 0 and 1, giving the minimum proportion of nucleotide positions a sequence must have in common with the reference sequence in order to be included in an alignment (default: 0.5)
