WebAfter global scaling, each inidividual gene won't necessarily have mean Z-score 0 and std 1, but your entire sample will. The benefit of global scaling is that, since you're transforming all genes the same way, you can compare expression between genes. However, if you have outliers in your sample (e.g. if some genes have really high expression ... WebMar 5, 2024 · Z-scores.

WebLast seen 8.6 years ago When you use the scaling capabilities of heatmap.2, the resulting plot heatmap shows a legend that says "Column Z scores" or "Row Z scores". The scaling looks as though the values have been normalized to SD units. z = (x - mean)/sd Is this what heatmap.2 means by a Z score? WebFirst heatmap contains z-score which is been calculated by heatmap.2 function with parameter "scale=row". While second heatmap I have generated is with values calculated by my own function name "normalisation" which also calculate the Z-score. Surprisingly output is different in both case.
