    Thx Prakhar,

    Sorry for my delayed response. The problem of viewing has been solved. Yeah, you are right, use ssh -X and it works! thx~

    I'm actually now trying larger-scale data on cluster, and would definitely ask for your kind help if come across new problems.

    best regard

      Is there anyone know the format of cnv result? For example:
      deletion chr10:6070441-6074520 4080 0.674906 0.00834134 72162.3
      It is very easy to understand the first three column mean, but is there any can explain the rest of column mean?

        Dear zhk,

        I had asked the same question to the author (Alex Abyzov), here is the reply.

        The output is as follows:
        CNV_type, coordinates, size, normalized_RD, p-val1, p-val2.
        p-val1 -- is from t-test
        p-val2 -- is from probability of RD valued within the region to be in
        the tails of gaussian distribution (kind a z-score).
        Regards,
        pg

          Thx gprakhar,

          Is that mean the larger of p-val1 and p-val2, the more confidence of the result?

          Do you find that the value of p-val2 will be very large or small sometimes? How to explain this situation?

          example:
          deletion chr10:6070441-6074520 4080 0.674906 0.00834134 72162.3

            Hello,

            I am not sure, have used the tool on simulated data only.
            You can ask the author and please do let me know what he says.

              Hello pg,
              This is the replay from the author.

              Those p-values are not very discriminate. The major cause of false
              positives is read mismapping and sequencing biases.
              Large events are generally more trustful

                Hi milesgr,
                I'm in the cluster and can not get into the root. How can I install the CNVnator?

                Thanks!

                  What do you mean by "cannot get into root". Have you downloaded ROOT package?
                  You'd better download the newest version of ROOT.(Old version may have bugs)
                  Then install CNVnator.

                  btw, ROOT is large package, you may take some patience.

                        Problems making CNVnator

                        Hi all,

                        I've got root installed, but now I'm having problems compiling CNVnator. When I type make, I get this error:

                        g++ -pthread -m64 -I/usr/local/root/bin/root/include -Isamtools -c cnvnator.cpp -o obj/cnvnator.o
                        cc1plus: error: /usr/local/root/bin/root/include: Not a directory
                        make: *** [obj/cnvnator.o] Error 1

                        Any help much apreciated.
                        Dan

                          Try simply by typing this:

                          Code:
                          export ROOTSYS=[path to root installed directory]
                          replacing everything inside and including the square brackets by whatever directory you installed root to - e.g. /home/djaffares/root
                          then type 'make' and hit enter and it should work! Good luck Dan!

                            CNVnator, still not compiling

                            Thanks for this, but still no luck. here is what I did:
                            which root
                            /usr/local/bin/root

                            export ROOTSYS=/usr/local/bin/root
                            cd software/CNVnator/src/
                            make

                            #And I still get this error.

                            g++ -pthread -m64 -I/usr/local/bin/root/include -Isamtools -c cnvnator.cpp -o obj/cnvnator.o

                            make: *** [obj/cnvnator.o] Error 1

                            #thanks in advance for any ideas :-)

                              You have to "cd" into CNVnator/src/samtools and then "make", so libbam.a is created.

                              Also remember to type

                              Code:
                              export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${ROOTSYS}/lib
                              Then type
                              Code:
                              cd ..
                              to get back into your CNVnator/src directory and type
                              Code:
                              make
                              again

                                Also does anyone know what bin_size refers to? There is a bin size as in the .BAM bin size, but there is also the genomic bin size...

                                  From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
                                  by SEQadmin2


                                  Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


                                  The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

                                  With the launch of new single-cell sequencing platforms in 2026, the field stands at an exciting inflection point. This article surveys the most impactful advances in the field and discusses how they’re reshaping research in cancer, immunology, and beyond.

                                  by SEQadmin2

                                  Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


                                  Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
