= [wiki:xQTL xQTL workbench] - Introduction =

xQTL workbench is a scalable web platform for the mapping of quantitative trait loci (QTLs) at multiple levels: for example gene expression (eQTL), protein abundance (pQTL), metabolite abundance (mQTL) and phenotype (phQTL) data. Popular QTL mapping methods for model organism and human populations are accessible via the web user interface. Large calculations scale easily on to multi-core computers, clusters, and Cloud. All data involved can be uploaded and queried online: markers, genotypes, microarrays, NGS, LC-MS, GC-MS, NMR, etc. When new data types come available, xQTL workbench is quickly customized using the Molgenis software generator.

== Availability ==
xQTL workbench is free and open source software, made available under the LGPLv3 license. xQTL workbench runs on most platforms, including Linux, Mac OS X and Windows. xQTL workbench can be rapidly customized using the Molgenis toolkit. See: MolgenisGuide
