importing fastq.gz to output emp-paired-end-sequences.qza

Running:
qiime tools import --type EMPPairedEndSequences --input-path /mnt/c/Users/kjharris/Desktop/CFMB2020 --output-path emp-paired-end-sequences.qza

There was a problem importing /mnt/c/Users/kjharris/Desktop/CFMB2020:

Missing one or more files for EMPPairedEndDirFmt: ‘forward.fastq.gz’

All three fastq.gz files are alone in the desktop folder:
barcodes.fastq.gz
forward.fastq.gz
reverse.fastq.gz

On a previous attempt Q2 provided the following: qiime tools import \

–type EMPPairedEndSequences
–input-path /mnt/c/Users/kjharris/Desktop/CFMB2020/EMPPairedEndSequences
–output-path emp-paired-end-sequences.qza
Imported /mnt/c/Users/kjharris/Desktop/CFMB2020/EMPPairedEndSequences as EMPPairedEndDirFmt to emp-paired-end-sequences.qza

Any thoughts on what I am doing wrong to run this initial script? I ran the q2 updates earlier today so I have updated to 2020.8 Thank you for any help!

I am wondering if I need to place the three fastq.gz files in a zipped folder?

I think that I had to create a zipped file before when I imported, but the zipped file does not seem to be recognized. I am using ubuntu

I updated my Mac to q2 2020.8 and I have the forward, reverse, and barcodes in a zip file on my desktop now, but I am still having trouble making the initial emp-paired-end-sequences.qza

Got it to work!

Glad you sorted things out @mudbugecology!

Just for posterity (to clarify for other users reading this topic), it looks like the issue is that you were pointing at the wrong directory:

But your files were not in /mnt/c/Users/kjharris/Desktop/CFMB2020, they were in /mnt/c/Users/kjharris/Desktop/:

Looks like you moved these all into a separate directory and got this to work:

:partying_face:

Thanks for sticking with it, and also for reporting back that you solved it!

Thanks, Nicholas! Glad to be back with another sample and running Q2. Have a wonderful Thanksgiving. Kyle
