    Will isaac2 perform on whole exome data as good as on whole genome data?
    Isaac2 will work well on exome. The multiplicative speed factor increase over other aligners will not be as high due to the fixed costs (reading in the index, demultiplexing) and the relatively small number of reads to align.

    In our experience, the variant calls from a whole genome assay are better than the variant calls from an exome assay, but that is due to factors such as coverage uniformity and not the aligner.

      OK .. index creation is running for hg19 ... I'll report back tomorrow.

      Btw, .. is starling2 (ivc) still the "variant caller to work with"? Or do you recommend other variant callers for isaac2-aligned data? I am just asking because it seems that there is not much development on github (sequencing) ...

        Any of the variant callers should work with Isaac BAMs. We have continued Starling (a.k.a Isaac variant caller) development, but it will take a bit more time for us to get the latest version on GitHub.

          I have asked Come to address the issues that you are seeing and to also start a new thread (or Google group) dedicated to Isaac support.

          Thanks,

            Posts related to isaac2 genome index creation have been moved into a new thread: http://seqanswers.com/forums/showthread.php?t=61539 to keep this thread focused on open source software from Illumina.

              Several more tools have now been added to GitHub.com/Illumina.

              Canvas: a tool for calling copy number variants that can be used in either germline data or tumor / normal samples.

              Hap.py: a tool for comparing VCF files by haplotype. This means that variants with multiple representations will still be matched correctly.

              pyFlow: a python module to manage tasks in the context of a task dependency graph. We previously used Make in this context, but developers have found pyFlow to be a much better experience.

                Can minimal/optimal hardware specs be noted on the respective pages so people can make an informed decision on whether they should try using that package. e.g. isaac (and possibly isaac2, going to try it soon) needs reasonably potent hardware.
                Thanks for the suggestion. we've added hardware guidelines to the latest manta update here:



                Hope this helps!

                  Hardware and system requirements for hap.py have been added here:

                  Haplotype VCF comparison tools. Contribute to Illumina/hap.py development by creating an account on GitHub.

                    We recently released Manta on GitHub under GPLv3.
                    In case people would like to take a closer look at how Manta works:

                    Preprint for our open-source Manta SV & indel caller (from DREAM SMC)
                    now on Biorxiv:http://biorxiv.org/content/early/2015/08/10/024232

                      Additional open source tools

                      Hi everyone,

                      we have just released Pisces somatic variant caller (manuscript in preparation) to our GitHub site. This method is used to call somatic SNVs, MNVs, and small indels in MSR and several BaseSpace applications. The analysis applies to targeted sequencing of tumor samples.

                      Other recent releases to the site include MarViN (used to refine genotypes in WGS data) and agg (used to rapidly merge gVCF files).

                      Thanks and happy holidays,

                      Semyon

                        Error with Canvas

                        Hi, I am trying to use Canvas for Germline WGS, and I am running into a fatal error. Could someone on this thread help me?

                        ERROR: Canvas workflow error: Illumina.SecondaryAnalysis.JobFailedException: mono returned error code -1

                          Yes, I have alerted the developers. They will likely ask you for additional details and the data set that you are using.

                              Could you perhaps share log files for the run, they should be in:
                              output\CanvasError.txt
                              output\CanvasLog.txt
                              output\Logging\*

                              One way to share these is to create a new issue on the Canvas GitHub page https://github.com/Illumina/canvas/issues/new and attach aforementioned files

                                The Impact of AI in Genomic Medicine
                                by seqadmin



                                Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

                                Multiomics Techniques Advancing Disease Research
                                by seqadmin


                                New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”
