  • Bfast

    Can you help me?
    I have read the paper about BFAST, but I am sure I can't index well. My data is about large genome (~2.7Gbp), and the source is mate-pair SOLID reads(length:50bp). I have created a reference genome in nt and another in cs. Now, I run command: bfast index -f hg19.fa -A 1 -m 111111111111111111 -w 18 -n 8
    another one: bfast index -f hg19.fa -A 1 -m 1111110011111110011111 -w 18 -n 8
    I got the under warnings from both them:
    Sorting by thread...
    ^M^H100.000 percent complete^Mthread 100.000 percent complete^MWaiting for other threads to complete...^MMerging sorts from threads...
    Out of 3 required merges, currently on:
    0^M1^M2^M3
    Merge complete.
    Sorted.

    Can anyone give me some suggestions about bfast index? I feel so hard to get it clean in my main. THank you!

    Looks like you don't have or you don't provide enough memory for the program.

      But I have about 300G RAM.

          I am so sorry for my hasty, but I will be mad for bfast index. Sorry for the cross posts.

            I would strongly recommend NovoalignCS for Solid data. I know it's commercial, but it's quite cheap and they do have a trial available. Otherwise algorithms for Solid data are fairly limited - and yes, we did test them all...

              Thank you. I will use the bfast after my groping it for several days.Maybe I will use NovoalignCS as your said while the bfast is hard to align more reads on ref.
              Thank you again.

                Genetic Variation in Immunogenetics and Antibody Diversity
                by seqadmin



                The field of immunogenetics explores how genetic variations influence immune responses and susceptibility to disease. In a recent SEQanswers webinar, Oscar Rodriguez, Ph.D., Postdoctoral Researcher at the University of Louisville, and Ruben Martínez Barricarte, Ph.D., Assistant Professor of Medicine at Vanderbilt University, shared recent advancements in immunogenetics. This article discusses their research on genetic variation in antibody loci, antibody production processes,...

                Choosing Between NGS and qPCR
                by seqadmin



                Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...
