Mx Scripts Library

GenomEUtwin
Development of this library of Mx scripts is financially supported by the GenomEUtwin project (European Union Contract No. QLG2-CT-2002-01254).
The GenomEUtwin project is a large scale study, including data from twin registries from eight countries, and is aimed at finding genes for body height, body weight, migraine, longevity, stroke, and cardiovascular disease. More information on GenomEUtwin can be found at the projects' website .

Working with the Mx scripts library
Feel free to use the scripts you find in the Mx scripts library. In case scripts contain original methodology, the relevant scientific references are mentioned in the script's header. All scripts are in the context of genetic data, unless specified otherwise (see e.g. the entries in "non-genetic scripts".

Disclaimer
It is assumed that the user of the scripts from the library has a basic understanding of Mx script language and model fitting approaches using twin data. The library is not set up as an online course in Mx or model fitting; not everything will be explained in detail. The user is expected to be able to customize the library scripts (e.g. changing data labels, fixing or freeing certain elements). Please read the relevant entries in the Tips section before you start. Although we run and check all scripts before they are made available online, they may still contain errors. If you encounter any errors, typos etc, please notify us by e-mail. Any corrections or newly added scripts are filed in the What's new section .

Registration
If you use scripts, please register. This allows us to keep track of the use and need for scripts. It will also allow us to notify you by e-mail when corrections or changes are made to the library.
