hi, look for cluster 3.0 and java treeview on the web using google.

you have to convert your excel file to a .txt file but this should be no problem.

you can use R

to import your data in R from excel, you've to export your sheet in csv format (tab delimited)

in R :

A <- read.table("your file.csv",header=TRUE,row.names=TRUE,sep="\t")
heatmap(as.matrix(A))

here's more info and examples : http://www2.warwick....cock/r/heatmap/

Please excuse me to bring an old topic up. However I need some help in getting the Microarray data (Excel sheet) in a format which cluster understand. Is there any possibility that someone can explain step by step the process from the beginning (Excel) to the end (Java Treeviewer). I really appreciate you help.
