CERVUS3.0说明书(4)

parentage analysis program整理自软件help文件,下载过的朋友可以直接在help里查看。

Cervus assumes that for all offspring the sex of candidate parents is either known or unknown. If sexes of candidate parents are known Cervus will attempt to assign to each offspring the most likely father, the most likely mother and the most likely parent pair. If sexes are unknown Cervus will attempt to assign the two most likely single parents and the most likely parent pair.

File types and file formats

Cervus uses a variety of different types of files. This page provides a list of these files and provides links to more detailed help on each type of file.

Input files

Cervus reads input data from files in comma-delimited (.csv) or tab-delimited (.txt) text format. If the file name does not have the suffix .csv is it assumed to be tab-delimited. All input files can readily be created in a spreadsheet package such as Microsoft Excel.

1. . A genotype file is used for allele frequency analysis, parentage analysis and identity analysis. It can be created by the user or converted from or to other formats.

2. . Simulation, parentage analysis and identity analysis can use user-defined allele frequencies instead of using an allele frequency file generated by running allele frequency analysis on a genotype file. The format of the file is the same either way.

3. . Parentage analysis requires a list of offspring to be tested. This file can also include known parents and candidate parents.

4. . In parentage analysis, if candidate parents are not included in the offspring file they can instead be provided in a separate file. This file can either contain a separate list of candidate parents for each offspring or a single list of candidate parents for all offspring.
