<p>The format of the raw data that upload in GEO is different, like TXT, CEL or other form. How can I extract the <strong>list of genes name</strong> from these formats? And then how can I normalize them with R?</p>

The format of the raw data that upload in GEO is different, like TXT, CEL or other form. How can I extract the **list of genes name** from these formats? And then how can I normalize them with R?

I would be really glad if anyone write **step by step** a complete set of codes for R with an example.

**Tags:** r, microarray, phylogenetics, data-download
