Hierarchial clustering and dendrogram

Thu, 10/10/2024 - 12:06 am

Hello,

Is there a way to perform hierarchial clustering in Igor and visualize as dendrogram? I have a 2D dataset where each column is mass spectra. I'd like to perform a hierarchial analysis to assess similarities between the spectra.

Thanks,

Peeyush

I don't know if it does what you want, but here is something:

HCluster and dendrograms were added in IP9. The documentation is pretty comprehensive.

And take a look at the demo experiment: File->Example Experiments->Analysis->Heat Map and Dendrogram
