I installed checkm using bioconda and downloaded pplacer from its site. I then moved all the pplacer executables into the checkm bin.

When I run this command:

$ checkm lineage_wf --pplacer_threads 2 checkm_input checkm_output

I get this output:

Please note that when I run this:

I get this location, where all checkm executables are:


Any ideas/ suggestions?

Why didn't you install pplacer from bioconda as well? Could you try installing both from bioconda and give it a try?

That was the first thing I tried but this is what the conda command returns
