parseDefaultQTLNames: Parse default QTL names.
In gact/shmootl: QTL Analysis Utilities for Yeast

Description Usage Arguments Value QTL Names

This function parses an input vector of default QTL names, and returns a genetic mapframe with the locus in each row derived from the corresponding QTL name in the input vector. An error is raised if any of the input values cannot be parsed as a default QTL name.

1	parseDefaultQTLNames(qtl.names)

qtl.names

Vector of default QTL names.

Genetic mapframe with loci corresponding to the specified QTL names.

A QTL name can be any valid item ID (see package overview). Default QTL names are of the form '04@33.0'. As with pseudomarker IDs, this indicates the chromosome and genetic map position of the QTL, where '04' is a chromosome ID and '33.0' is the position of the given QTL in centiMorgans.

In a default QTL name, the minimum precision of the map position is one tenth of a centiMorgan. As in R/qtl, if the map step size is smaller than this, the default QTL name is adjusted to match the appropriate level of precision.
