[limin321]

Hi

I am trying to use roary_plots.py to visualize my phylogenetic tree, so I run the command following, however, there is an error saying: No module named 'matplotlib' . Does anyone have any suggestion how to solve this issue.

Your help will be really appreciated.

(agro) KluepfelLabMBP01:results dklabuser$ python roary_plots.py usage: roary_plots.py [-h] [--labels] [--format {png,tiff,pdf,svg}] [-N SKIPPED_COLUMNS] [--version] tree spreadsheet roary_plots.py: error: the following arguments are required: tree, spreadsheet (agro) KluepfelLabMBP01:results dklabuser$ python ./roary_plots.py --labels accessory_binary_genes.fa.newick gene_presence_absence.csv Traceback (most recent call last): File "./roary_plots.py", line 64, in import matplotlib ModuleNotFoundError: No module named 'matplotlib' (agro) KluepfelLabMBP01:results dklabuser$

Thanks a lot. Best,
