No reads in the "Final output files created"

Dear forum members,

I am not getting any reads in the final steps of Kneaddata. It works well with the demo data but does not work with my own data. Please see the line count in the output files. I have also pasted the log file at the end. Any suggestion would be highly appreciated.

were you able to resolve this ? if so, kindly help me as well.

`
this is telling us the reads are not paired

is reordered_n1ymom5c_reformatted_identifiersqe83rdy8_s34_R1 truly the pair to reordered_5qwugmx9_reformatted_identifiersfsonvs4e_s34_R2 ?

Maybe checking your input data might reveal something…

hope it helps
