Cvt2Mae Basics

In order to use the MAExplorer data-mining tool on your cDNA array data, you must convert your data files into the data formats described in Appendix C and Appendix D of the MAExplorer reference manual. Although this maybe done by editing user's data files by hand into the required formats, it is a non-trivial process. Therefore we have developed a "wizard" conversion tool called Cvt2Mae to automate these conversions.

Cvt2Mae is a Java program designed to make it easier for use by researchers to use MAExplorer by helping them convert their data into the MAExplorer format. Cvt2Mae handles commercial chips such as Affymetrix, as well as other standard formats such as GenePix and Scanalyze or one-of-a-kind custom academic chips (<User-defined>). In addition, you may specify the fields of interest for the "Print file" or (GIPO or Gene-In-Plate-Order) file, and the fields containing the quantified data.

The Cvt2Mae converts specific chip information you entered into what we call an "Array Layout". This Array Layout file may be edited and saved for use in future conversions and shared with collaborators. Essentially, the Array Layout contains a set of "rules" for converting the user's data. After you have filled out the forms in Cvt2Mae, it will generate the set of converted data files and directories to be used directly with MAExplorer.

Cvt2Mae Data Conversion Steps and Tutorials

There is a detailed description on using the Cvt2Mae converter that provides the level of detail you need to use it effectively.

There are several slide shows describing how to use the Cvt2Mae to convert various data sets. They consist of a series of screen shots from Cvt2Mae that go through each of the steps on how to set up the parameters and convert your data. There are two for Affymetrix data, one is a downloadable PDF and other an extensive online version.
