Creating heatmap using hclust2

Microbial community profiling MetaPhlAn
1

Hello, I am trying to generate the heatmap using hclust2 but ran into an error

ValueError: The number of observations cannot be determined on an empty distance matrix.

When I looked back at my file of merged_abundance_table_species.txt, indeed, it only has Body Site header and the bacterial strains. There were no numbers/digits next to the strains.

How do I solve this issue with the merged abundance table species?

Thanks in advance.

Regards,
Win Ning.

Hi @WinNing
How have you generated the merged abundance table?

Hi,

I’ve already solved the issue! I was only using one sample to plot the heatmap but when I tried multiple samples, it ran fine!
