  • number of contigs in velvet

    hi all , what is the approximate total number of contigs we should get in a velvet assembly? I would like to know this because i did assemblies with various parameters but i always get more then million contigs..

      In a genomic assembly you should get exactly the number of chromosomes for that species or you've made a horrible mistake.

      Seriously, i think you are beginning to shoot from the hip with your questions to this board. Post some more specifics or do some research on your own.

        What are you trying to assemble?

        Here are some numbers from CLCbio tool: http://www.clcbio.com/index.php?id=1413

        Lesser, longer contigs are better, provided they are not incorrect!

              Yes, it's better we know the exact chr number. But not all the organisms we know their chromosome. A good way is to align to a closely related organism and then to check the left contigs.

                Strategies for Sequencing Challenging Samples
                by seqadmin


                Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
