DESCRIPTION
delrious
is a computer program that accepts as input data representing codominant, single locus, diploid molecular markers
(e.g.,
microsatellites), applies to them the algorithm that is described in Lynch, M. & K. Ritland. 1999. Genetics 152:1753-1766, and returns delta and relatedness estimates.
delrious
can implement bootstrap and jackknife resampling procedures to provide confidence measures. Syntax templates for running analyses are contained in a notebook that distributed with the code.
delrious
uses the technical computing environment
Mathematica
(Wolfram Research, Inc. 2000) as a software platform and can be run under Linux, Macintosh, Microsoft Windows, or Unix operating systems.
delrious
was composed by J. Stone & M. Björklund (2001. delrious: a computer program designed to analyse molecular marker data and calculate relatedness and delta estimates with confidence. Molecular Ecology Notes 1:209-212).
IMPLEMENTATION
Data should comprise paired rows containing numbers representing allele sizes at various loci in individuals; datafiles may be prepared using spreadsheet software and saving them as Tab delimited text files.
To run
delrious
4-8 parameters are entered:
path where data to be analysed reside
(e.g., "HAL900/DATA/datafile.txt")
The parameter 'location for output' defaults to 0 (none); if the output is to be stored in a file, then a filename should be provided.
loci number
(e.g.,
17)
initial locus to be included
(e.g.,
2)
final locus to be included
(e.g.,
16)
location for output (optional; 0 = none,
(e.g., "HAL9000/DATA/datafile.out")
allele proportions to be used (optional; 0 = allele proportions calculated from data, lists input by user)
format for terminal output (optional; 0 = lists, 1 = matrices)
estimate(s) returned (optional; 0 = relatedness estimates, 1 = relatedness and delta estimates).
The parameter 'allele frequencies to be used' defaults to 0 (allele frequencies obtained from data); if allele frequencies obtained from other sources are to be used, then they should be input according to syntax templates.
The parameter 'terminal output format' defaults to 0 (lists); if matrices are desired, then a 1 should be input (displaying matrices becomes unwieldly for data including many individuals;
e.g. ,
matrices containing many comparisons).
The parameter 'estimate(s) to be provided' defaults to 0 (relatedness estimates); if relatedness and delta estimates are desired, then a 1 should be input.
OUTPUT
Output comprises pairwise comparisons between individuals; these are stored as elements in a triangular matrix that can be read by spreadsheet software
(e.g.,
Microsoft Excel).
r estimates are returned first;
delta estimates (if desired) are returned second.
