Can anyone suggest a website, book or paper which explains hows to read/understand a heat map. I have been asked to read on this topic. Each cells in a heat map represents the expresison of a gene and teh expression intensity is colour coded e.g. red for high expresison etc. But my main cincern is that when peope publish a heatmap, all teh reader see's a bock of red,yello and green colours. It doens[t show eh name of a gene etc does it?
Also, what do thw rows and columns represent. Do each row reprent a different gene and each gene represents the expresion of the same gene across different variables?
