Polypolish error

[ayoraind]

Just a quick note on the FAQs

Can I assemble more than one genome at a time?

If you would like to assemble more than one genome using Dragonflye, I would recommend you do this with [Bactopia](https://bactopia.github.io/). Bactopia will allow you to process a single genome or thousands, and it also includes many other bacterial genome analyses. If you don't want to use Bactopia, I suggest you see the next question!"

You could also include a note in the above statement about the bacass Nextflow pipeline (https://github.com/nf-core/bacass), which uses Dragonflye (or other select assemblers) to assemble more than one genome.

Thanks once again for your excellent pipeline.

I see from this section (https://github.com/rpetit3/dragonflye/blob/main/bin/dragonflye#L416) that the current version of dragonflye has the correct Polypolish sub-command. So, I edited that section of the dragonflye script. Everything now works correctly. I guess the dragonflye version from nfcore (https://github.com/nf-core/modules/blob/master/modules/nf-core/dragonflye/environment.yml) needs to be updated accordingly.

Hi @ayoraind

Thank you for letting me know about this, and I'm glad you found a solution.

I'm curious what error v1.2.0 was giving you on the install. I wonder if I need to make a fix on the recipe on bioconda

Thanks again!
Robert

Hi @rpetit3,

I am not entirely sure what to infer from the error message on dragonflye v1.2.0 installation trial. I show you the exact error message below:

On the other hand, I was able to conda install the previous version (dragonflye v1.1.2) without any issue.

Hi @ayoraind

Looks like it might be a conda issue. I'm able to solve the environment using conda version 24.3.0, but not on version 23.7.3.

I think its related to conda 24 using libmamba, so in your case if its possible to upgrade or use mamba I think you'll be able to use v1.2.0.

Cheers,
Robert

Hi @rpetit3,

Many thanks. I updated my conda version as you suggested and re-ran dragonflye (v1.2.0). Everything works perfectly.

Ok I added mention of bacass is the alternatives.

Going to go ahead and close this, feel free to reopen
