Hi everybody I want to merge reads (reverse and forward) so i use seqPrep with this command :

 SeqPrep -f ERR770964_1.fastq -r /ERR770964_2.fastq -1 forward.fastq -2 reverse.fastq -s merged_file.fastq

, i got this result

Pairs Processed:        0
Pairs Merged:   1066735
Pairs With Adapters:    12980
Pairs Discarded:        6788

Even though your file names say .fastq it looks like your files may be compressed/gzipped. What do you get if you do file ERR770964_1.fastq and file ERR770964_2.fastq?

My files is not compressed , it's fastq file i don't indrstand when i have problem

[GenoMax]

I asked you to provide output for the two commands above. Without that there is not much we can say.

If you are Linux user try zcat merged_file.fastq you can decompress via gunzip merged_file.fastq, then open it
