Related Issue

I found some users alway get zero file of two paired files [issue1]
(https://forum.biobakery.org/t/paired-end-data-results-in-unpaired-output/928/2) [issue2]
(https://forum.biobakery.org/t/no-reads-in-the-final-output-files-created/3419).
I also have that issue, my sequence label was like
R1: @A00456:506:H5GC2DSXY:1:1101:6027:1000 1:N:0:CAACACAG+CAAGGTAC
R2: @A00456:506:H5GC2DSXY:1:1101:6027:1000 2:N:0:CAACACAG+CAAGGTAC
So. in old "get_reformatted_identifiers adding" "#0/1" and "#0/2" not solving this issue. and I just delete the part. it worked.

Can this be resolved? I have to modify kneaddata manually on reinstalls to modify this code otherwise.

@brett-van-tussler I hope the developer have noticed this promote. But my poor commit method may cause some conficts. you can check the new version of kneaddata.
