GACD Version 1.2

GACD: Integrated Software for Building Genetic Linkage Maps and Mapping Quantitative Trait Genes in Clonal F₁ and Double Cross Populations

Current version: V1.2; Released 12 July 2019;Updated 20 September 2019.

Version history: v1.0 released July 2014; v1.1. released January 2016

What’s new in version 1.2? (1) A new functionality was added to convert the SNP genotypic data to the software format, which was called SNP, and listed as the first functionality of the software. By using the SNP functionality, genotypes AA, TT, CC, GG, AT, AC, AG, TC, TG and GT will be converted to genotypes which are required by the software. Users need to provide SNP genotypes of the two heterozygous parents of clonal F₁ or four inbred parents of double cross to use this functionality. (2) In functionality CDM, the estimated recombination frequency and LOD score were recorded in a temporary external file, in order to increase the capability to handle the large number of markers. In current version, the maximum number of markers can reach 20,000 to 40,000. For markers more than 10,000, we suggest to use functionality BIN to remove the redundancy. (3) In functionality CDM, ordering algorithm was optimized. (4) Both 32-bit and 64-bit versions were provided.

Technical development of GACD: The software is project based, where kernel modules for building linkage maps were written by C#, those for QTL mapping was written by Fortran 90/95, and the interface was written by C#. It runs on Windows XP/Vista/7/10, with .NET Framework 4.0.
