Analyse microarrays with Fred's softwares

You will find on this website free tools to analyse microarrays. The analysis steps are :

1- Select the most sensitive probsets and convert them into gene names with Collapse microarray

2- At this step data are generally log(2) transformed (log(x)/log(2)) to normalise the distribution. Compare two groups of data and calculate the corresponding fold change and Pvalue with Pvalue and fold change calculation

3- Select sublists of significant gene names upregulated, downregulated or both with Create sublists according to numerical values

4- Put gene synonyms into one column with Reorganize genes synonyms

5- Compare your significant lists of deregulated genes with biological functions databases with AutoCompare ZE

Enjoy ! ;)
