Hello,
I am trying to follow the tutorial to use qiime2 output to analyze in picrust2 plugin. qiime2-session/hands-on-pricust2.md at master · mbcarbonetto/qiime2-session · GitHub
I am stuck in the first step of placing te ASV against the Picrust2 references
I am using Qiime2-2021.11,
This is what I add
qiime fragment-insertion sepp
--i-representative-sequences representative_sequences.qza
--p-threads 1
--i-reference-database reference.fna.qza
--o-tree phylogeny
--output-dir picrust2/results
and this is the error
There were some problems with the command:
(1/2) Invalid value for '--i-reference-database': Expected an artifact of at
least type SeppReferenceDatabase. An artifact of type
FeatureData[AlignedSequence] was provided.
(2/2) Missing option '--o-placements'. ("--output-dir" may also be used)
The second error is the easier one to address. If you put --output-dir picrust2/results you can not put any parameter with a --o at the beginning.
I think that tutorial you are using is a bit outdated. Its last commit on github was 2019 and q2-fragment-insertion has been updated since then. The tutorial you linked uses this command:
