comparing multiple gene sets with expression values

Question

Hi

who knows how we can compare multiple samples with different genes and different fold change values and create a heatmap like this ;

If you already have the fold-changes, a heatmap like this can be made in MicroSoft Excel or LibreOffice Calc, among others.

But you would get more helpful answers if you explained what kind of data you have, possibly providing small examples.

Thanks for the answer, I have 16 different expression sets like this:

Mocs2 40.6 64.4

H4c1 64.1 80.1

Smndc1 70.5 95.8

Hsp90a 107.8 63.3

and they have different genes (around 40 genes in common between each data set). I need to calculate the fold change between them and compare the common genes between all conditions in terms of foldchange and possibly the function of those genes in different GOs.
