Comparison of GenomeStudio software versions

This article describes the differences between GenomeStudio 2011.1 and GenomeStudio 2.0 and how to determine which version is appropriate for the intended type of analysis.

Use this table to select the appropriate GenomeStudio software version for array analysis.

	GenomeStudio 2.0	GenomeStudio 2011
Array type	Genotyping and Cytogenetics	Methylation
Modules available	Genotyping	Genotyping*
	Polyploid	Methylation
		Gene Expression**
GenTrain version	3.0	2.0

License keys for GenomeStudio 2011.1 are in the GenomeStudio 2011.1 license keys.txt file included with the installer.

*The Genotyping Module in GenomeStudio 2011.1 uses the older GenTrain 2.0 algorithm and does not support GenTrain 3.0. Therefore, a cluster file created in GenomeStudio 2.0 cannot be used to create a project in GenomeStudio 2011.1.

In summary, GenomeStudio 2011.1 is recommended for methylation projects only, and GenomeStudio 2.0 is recommended for genotyping projects.

**Illumina no longer produces Gene Expression BeadChips.
