OneMap

OneMap is a software for constructing genetic maps in experimental crosses: full-sib, RILs, F2 and backcrosses. It was developed by Gabriel R A Margarido, Marcelo Mollinari and A Augusto F Garcia. Later on, Rodrigo R Amadeu and Cristiane H Taniguti joined the project.

It has been available on CRAN for several years (https://cran.r-project.org/package=onemap). Its last version was updated on 2017-10-18. CRAN has OneMap's stable version, which is recommended for most users.

This github page has its version under development. New functions will be added (experimental work) and, once it is done, we will synchronize the repositories and add it to CRAN.

We worked very hard to release a new stable version allowing users to analyze data sets with markers based on sequencing technologies, such as Illumina, GBS, etc.

OneMap comprises a set of functions that allows users to build a linkage map. Some functions are used internally by the package, and should not be used directly.

How to install

From CRAN (stable version)

It is easy, just type (within R):

setRepositories(ind = 1:2)
install.packages("onemap", dependencies=TRUE)

You also can use the console menus: Packages -> Install package(s). After clicking, a box will pop-up asking you to choose the CRAN mirror. Choose the location nearest to you. Then, another box will pop-up asking you to choose the package you want to install. Select onemap then click OK. The package will be automatically installed on your computer.

OneMap can also be installed by downloading the appropriate files directly at the CRAN web site and following the instructions given in the section 6.3 Installing Packages of the R Installation and Administration manual.

From github (version under development)

Within R, you need to install and load the package devtools:

install.packages("devtools")
library(devtools)

This will allow you to automatically build and install packages from github. If you use Windows, first install Rtools. If you are facing problems with Rtools installation, try to do it by selecting Run as Admnistrator option with right mouse button. On a Mac, you will need Xcode (available on the App Store).

Then, to install OneMap from github (this very repo):

install_github("augusto-garcia/onemap")

From docker hub

OneMap requires several dependencies that you may not have in your system. To overcome the need of installing all of them, you can use the OneMap image in docker hub. Install docker (see more about here) and use:

docker pull cristaniguti/onemap_git:v2.1.1008
