I am trying to run jellyfish. I run count and have a result file like *.jf. I have implemented the *.jf file in histo command. but in *.histo result i have found nothing, a 0 byte file. here are command line:

jellyfish count -t 20 -C -m 21 -s 1G -o CL_2578_2b.jf --min-quality=30 /mnt/disk2/Lab_Users/Kishor/genomes_raw/all/trimmed/CL_2578_2b_R1.fq /mnt/disk2/Lab_Users/Kishor/genomes_raw/all/trimmed/CL_2578_2b_R2.fq

jellyfish histo -t 20 CL_2578_2b.jf -o CL_2578_2b.histo

I have tried many times, but each time find the histo result as 0 byte, nothing inside. i am also attaching the count result. Can someone please help me to fix the issue?
