The Hierarchical Clustering Heatmap tool in MetaboAnalyst initially creates accurate heatmaps, but when I try to export the image as a PDF or PNG file, it generates the wrong heatmap. For example, when I select Ward as my clustering algorithm and Euclidean as my distance measure and don’t change any other default parameters except for selecting the option of displaying top 25 features, the heatmap created and exported will be correct. If I were to change my distance measure only to Pearson or Minkowski, it downloads the incorrect heatmap which is based on Euclidean.
(On a separate note, one thing which would be helpful in the future is the addition of being of able to view the number of samples and their distribution within each cluster in the heatmap.)
Thanking you in advance!
