methods for processing fungal ITS2 data in QIIME2

i really realy tired to trim my its2 data using itsx, and i got error :
Error: QIIME 2 plugin ‘itsxpress’ has no action ‘trim-pair-output-unmerged–i-per-sample-sequences’.

Welcome @Pena_Piana!

Looks like you are just missing a space after “unmerged”

Good luck!

Hi @Pena_Piana,
Could you please report the full error message? See this line:

Or re-run with the --verbose flag.

Also, please do not post duplicate questions. You posted the same question twice, and I had to merge both into this topic. I also merged your third post into this topic, as it is a question about the same method.

Thanks!

thank you for your help. …
I got this error below, what I should do to fix this error message. thank you

(qiime2-2020.6) [email protected]:~/Documents/alfri$ qiime itsxpress trim-pair-output-unmerged --i-per-sample-sequences sequences.qza --p-region ITS2 --p-taxa F --o-trimmed trimmed.qza
Plugin error from itsxpress:

Hi @Pena_Piana,
That still does not look like the full error message, please note my requests above.

In any case, I am not the itsxpress developer and cannot help troubleshoot, just trying to help you report the full necessary info. Maybe @Adam_Rivers could give you a hand if you report the full error message

@Pena_Piana My guess from this info would be that you need to update BBtools in your Qiime2 environment. With your Qiime environment active, run conda install -c bioconda bbmap.
