Too many genes!

Postby Curious George » Fri Aug 29, 2008 3:04 pm

Dear Mikael,

I want to use GenEx to analyze microarray data with geNorm and Normfinder. I have 12 arrays and 5707 genes. In the manual there is information that, " The input file should be an Excel data file with the first column containing the sample names and the first row containing the gene names." Since I have 5707 gene names I have a problem because Excel 2003 does not allow so many rows (original geNorm does not work in Excel 2007). Can I not analyze my data?

Thanks for your help and interest.

Best wishes
Curious George

This limitation in Excel is easily overcome by arranging the data transposed in Excel (i.e., with the 5707 genes as rows and the 12 samples as columns), read the data into GenEx and then transpose them in GenEx (just click the transpose button). GenEx handles any number or columns/rows.

Good luck!
