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.

`  
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
