Sorry @colinbrislawn I was writting the post but I didn't want to post it in that moment, but I did so accidentaly. Therefore, many information is lacking.
The problem I have is that I want to use my data to assemble weights using q2-clawback in order to train a classifier as said here (Using q2-clawback to assemble taxonomic weights) in "assembling more exotic weights".
I'm having problems with the following command:
qiime clawback sequence-variants-from-samples
--i-samples samples.qza
--o-sequences sv.qza
The input demands a feature table, and after giving it I get the same error:
Plugin error from clawback:
Invalid characters in sequence: ['0', 'd', 'e', 'n', 'o', 'v'].
Valid characters: ['H', 'R', 'N', 'M', 'W', 'D', '-', 'V', 'S', 'K', 'T', '.', 'B', 'Y', 'G', 'A', 'C']
Note: Use lowercase if your sequence contains lowercase characters not in the sequence's alphabet.
Debug info has been saved to /tmp/qiime2-q2cli-err-gf1h38lt.log
I tried to change of table many times, even with qiime2 tutorial tables (just for testing), but I still get the same error (only with different invalid characters).
I don't know if I'm providing a wrong input.
Thank you very much, I hope I explained well this time!
