Hi,

I am in this situation:

Find genes correlate with a given gene in gene expression heatmap(data analysis)

I have two genes of interest (with 0.72 correlation to each other). I would like to find set of genes or cluster of genes that are correlated with these two genes? Is there any way to have a heatmap of top 5 correlated genes to my two genes of interest?

I have input of like this:

Genes   MygeneinterestA MygeneinterestB
DDR1    0.0634830504    0.0054455272
GUCA1A  -0.0131271582   0.053572876
UBA7    -0.1101264403   -0.0797316737
PTPN21  -0.2523412388   -0.2177850957
EPHB3   -0.0640084764   0.0527953252
TRADD   -0.0499531048   0.1662949165
PLD1    -0.0599397513   -0.2011697957
FNTB    -0.2625271489   -0.3401681914

Thanks,

What are the numbers in your table?

these are the correlation values calculated from the expression values. The table shown here is just the transpose one.

So you just need to select the 5 highest values in that table?

if I do that, so these are those five genes that highly correlated with my gene of interest....,,,!!!????

You calculated correlation coefficients and then select the most correlated genes, no? Are you confused?
