    Hi Xian:

    Thank you for your information. We already saw our dataa. It is different from Illumina.
    And we try to modify the original code, but failed. The results is wrong. And the author of that software still not give us response. I still wait!

    Best

      Hi Jigang,

      Which software do you mean? BreakDancer? Which email did you send the question to?

        Hi Xian:

        It is breakdancer. I post my question to mail-list of breakdancer, and write a email to Dr.Chen and a sample of our data.
        By the way, are you Dr.Xian Fan? If it is you, I am sorry that I did not know that. So could you please help me about our problem. Thank you so much!

            Hi Jigang,
            Sorry for late reply,
            I personnaly use IGV and tablet for viewing bam files.
            Regarding the use of the data with breakdancer, I did not the time to look at that, if the bam file you are using could be made available on an ftp, i could take a look at it.

              Hello Everybody,

              I am running into problem using breakdancer to find somatic rearrangements. I followed the command on the following website:
              http://breakdancer.sourceforge.net/pipeline.html

              However, my results are only from one "lib".
              The result .ctx file has a typical line like:
              chr1 121355199 5+4- chr11 51570084 25+93- CTX -525 68 3 NA2|3

              Here is less-ing my config file:
              readgroup:TU platform:illumina map:../cpp/0872r1_1_2_sequence.txt.sol2std.fq.sam.sort.bam.rmdup.bam readlen:100.00 lib:NA1 num:10001 lower:276.52 upper:446.96 mean:364.27 std:21.33 SWnormality:-53.69 flag:0 exe:samtools view
              readgroup:NA platform:illumina map:../cpp/0871_1_2_sequence.txt.sol2std.fq.sam.sort.bam.rmdup.bam readlen:76.00 lib:NA2 num:10000 lower:313.32 upper:660.06 mean:525.81 std:43.58 SWnormality:-72.27 flag:0 exe:samtools view

              Here is the output HEADER looks like:
              #Software: BreakDancerMax-1.1r112
              #Command: ./breakdancer_max -t -g 0872bed -d 0872pair.ctx -q 10 ../perl/0872pair.cfg

              ...
              ...

              thank you all in advance for looking into this.

                I've noticed that bam2cfg.pl only works for some of my bam files when I use the default mapping quality but not a more lenient threshold.

                perl bam2cfg.pl -q 35 s_6.pe.sorted.bam
                readgroup:NA platform:illumina map:s_6.pe.sorted.bam readlen:51.00 lib:NA num:1555 lower:0.00 upper:674.20 mean:294.0std:84.74 exe:samtools view

                However, using a mapping quality lower than default results in no sdout. There are reads of lower mapping quality in my bam file, and the bam file is sorted/indexed.

                perl bam2cfg.pl -q 20 s_6.pe.sorted.bam
                <blank>

                Any ideas?

                These are Illumina Ga2 PE 101bp reads, single library. No @RG info in the header.

                  Does BreakDancer work for Exome PE Illumina data?

                    Recent Advances in Sequencing Analysis Tools
                    by seqadmin


                    The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

                    Essential Discoveries and Tools in Epitranscriptomics
                    by seqadmin




                    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
