Demultiplex - No barcodes and Forward Reads

Dear All,

I am having some issues during the demultiplex stage:

qiime demux emp-single
–i-seqs emp-single-end-sequences.qza
–m-barcodes-file sample-metadata.tsv
–m-barcodes-column BarcodeSequence
–o-per-sample-sequences demux.qza
–o-error-correction-details demux-details.qza

Q1- Is there any method to demultiplex without associate to barcode (In Qiime 1.9.0 I used the –i folderpairedsequence –o outputfolder –demultiplexing-method sampleid-by-file? Is there any similar command like this one in QIIME 2?
I have a folder with the paired files and another with the Mapping File (Metadata).
How can I do the demultiplex without the metadata and barcode files, like this command in QIIME 1.9.2

I would greatly appreciate for any clarification.


Hello Andre,

Good afternoon.

Yes! Check out the import guide for the fastq manifest format, as it works a lot like the script and gives you even more control over sample names.
