qiime feature-classifier classify-consensus-vsearch error

[Asha1]

Hello

I have problem with qiime feature-classifier classify-consensus-vsearch taxanomy analysis. There are so many fasta sequence id starts with 465. I don’t know for which Id it has no taxonomy reference data.
Could anyone help me how to sort out this problem?

This is the error I got

Hello!
I’m new to the forum, so I hope to be following the rules. I was about to post a new topic about a similar error, but since this was recently posted, I figured it’s easy to ask here.

I get the same error as @Asha1 when trying to use classify-consensus-vsearch with MaarjAM as a reference taxonomy (see full command below), suggesting the ids in my reference reads and reference taxonomy don’t match (see error detail below). However, after checking both files for mismatches I found none. Moreover, my error message says ‘identifier 517’, even though my sequences are all named with the full GenBank ID (e.g., AB749517). I also checked for spaces that could be interfering with the code, but again, nothing.

Someone reported a similar problem here, but that user did find a mismatch. I also tried everything else suggested in that topic, but I still get the error.

One last detail: To prepare my MaarjAM files for qiime, I followed the instructions of a generous github soul. Interestingly, when I tested vsearch with his files (unfortunately out-of-date now), it worked perfectly. And since I followed his R code to prepare and check both my fasta and id-to-taxo, I’m suspecting the error comes from one of the new sequences.

I’m wondering what should I check next if there are no evident mismatches. Could something else be causing this error?

Thanks in advance for your time,

mica

Hello again @Asha1 and welcome to the forum @mica.tosi !

I apologize both for the delay, I was out of the office.

I’m new to the forum, so I hope to be following the rules. I was about to post a new topic about a similar error, but since this was recently posted, I figured it’s easy to ask here.

Yes thanks indeed for asking in this topic! It seems you have identical issues so asking here will save us all time. And thanks for troubleshooting this a little bit and providing details on your process.

This issue is almost always caused by formatting issues, occasionally very cryptic issues. So we usually only see this crop up when someone is generating their own reference database since the kinks have mostly been worked out for commonly used databases — or when the reference sequences and taxonomy really do not match (honest mistakes happen!)

So with that in mind please see this:

Feature classifiier consensus vsearch - key error

Thanks for sharing! This one stumped me for a while because your files look fine to the naked eye, have the same number of entries, etc, and I don’t have your query sequences to replicate the exact error you have. But I believe I discovered the problem: Your fasta file (but not your taxonomy file) contains invisible special characters (^M) at the end of the accession #s (this is a windows newline character). vsearch seems to be interpreting this newline character as part of the accession # a…

My hunch is that you both could have this same issue with invisible line breaks causing formatting issues. Want to take a look and report back?

[mica.tosi]

It worked! I converted the fasta with dos2unix before importing and it ran smoothly.
Couldn’t be happier.
Thanks a lot
