Whoa! Something looks mighty strange with that barcode ID. Would you be able to share your emp-paired-end-sequences.qza and sample-metadata.tsv? If you are unable to publicly share feel free to send a DM. If you are unable to share your data at all, can you please rerun the command, with --verbose included, and copy all of the output?
Hello,
I am having the same issue and I looked at all of my files and it seems as if one sample that is present in the forward and reverse files is not present in the barcodes file.
Is there a reason for this and am I able to fix it?
I attached both my files below
Hi @megladds - looks like only your metadata was attached - would you be able to share your sequences artifact, too? Feel free to send along as a direct message to me if you are unable to post publicly. Thanks!
I emailed you using the email on your github page, but here is the google drive link as well (it should be accessible by you).
(how would I direct message you on this forum?)
Those should all match up, but you can see here, you are missing the second record (@M01522:85:000000000-AU4UD:1:1101:18045:1364 1:N:0:2) in your barcode file.
I then went ahead and checked the line count in each file (they should all be the same):
Looks like you are missing some records in your barcodes file! I would suggest contacting your sequencing facility (or whoever prepared these files for you) and see if they have any thoughts.
Good luck and keep us posted!
