Hi @jphagen,

Thanks for your reply. I have made some progress, however, im running into other problems now.

I figured out, that when using Galaxy, the use of an manifest is not possible. [q2-galaxy file import troubles - #4 by colinbrislawn](https://forum.qiime2.org/t/q2-galaxy-file-import-troubles/24404/4)

So, I try using the casava format on my samples. This is an example of a file name: 2\_D08\_89711-D08\_CGAGGCTGACTGCATA\_L001\_R2\_001\_KFPJJ.filt.fastq.qz

Im not sure if this is the right format. I'm now uploading using SequenceswithQuality, and pairing the collection as suggested by [improving fastq import experience for Galaxy users - #2 by gregcaporaso](https://forum.qiime2.org/t/improving-fastq-import-experience-for-galaxy-users/29046/2), and then using the casava format. I get an error saying: Unexpected error importing data:  
Missing one or more files for CasavaO  
neEightSingleLanePerSampleDirFmt: '.+  
\_.+\_L[0-9][0-9][0-9]\_R[12]\_001\.fast  
q\.gz'

1. What method of uploading do I use with my paired samples, with names like: 2\_D08\_89711-D08\_CGAGGCTGACTGCATA\_L001\_R2\_001\_KFPJJ.filt.fastq.qz
2. What method of importing do I use, and what type can I use when not using a manifest?  
3.What does this error code tell me?

Thanks in advance!
