PPanGGOLiN TypeError: Population must be a sequence. For dicts or sets, use sorted(d).

Hi !

I get this error and I can't debug why it happens, the input files look good to me

TypeError: Population must be a sequence. For dicts or sets, use sorted(d).

I'm using ppanggolin like this: ppanggolin workflow --anno list_genomes.tsv -c 64 -o output --clusters clusters.tsv --infer_singletons --rarefaction

Thanks in advance ! Eric

Hi !

Any chance you could provide the complete log? It's nearly impossible to identify the location of the problem without the full trace (which should be in the log file where this error is written) with something as generic as this kind of error.

Hello,

Sorry for the very little info, this is the log file obtained on that run: debug_log.txt

And here is the complete error message: error.txt

Thanks !

I see, thanks a lot !

This is definitely a bug, and I think it's related to having exactly the number of genomes that you have in your run here (501?). In the meantime, until we resolve this, I believe that increasing the chunk_size in the "partition" step might fix this error.

Indeed if I remove one genome from the list it works fine, haven't tried the chunk_size yet.

Hi,

Sorry for the delay.

This bug was resolved in PR #273 and released in version 2.1.2: https://github.com/labgem/PPanGGOLiN/releases/tag/2.1.2.

Updating your PPanGGOLiN version should fix this bug.

Best,
Jean
