De novo assembling and scaffolding

[Rahul shelke]

Hello all,
I am working on plant genome sequence assembling and scaffolding.
I am done with assembling with the help of velvet, but getting error when I am using opera Scaffolder. As instructed in opera scaffolder site I am having reads files forward and reverse in fastq format, contigs.fa file generated from velvet G.I tried to put my data information in opera command line but i got error message .
At the present situation i exactly don't know how to write command for my data in Opera. I would be very grateful if anyone could shade some light on my problem.

Thanks...............
Rahul
