    how to do methylation analysis using pacbio data

    I want to do methylation analysis based on pacbio .bax.h5 data. I already mapped the .h5 data to the reference genome and got .cmp.h5/.sam results.

    In order to get IPD information, I knew from the pacbio website that kinetics tools can be used for extracting IPD from .cmp.h5. But I couldn't find detailed documentations of how to install/use the kinetics tools.

    Has anyone ever used such tools to get IPD information and corresponding analysis of methylation? Or are there any other methods for these analysis?

    Thanks a lot

    By far the easiest way is to use Pacbio's complete software suite, https://github.com/PacificBiosciences/SMRT-Analysis, http://www.pacb.com/support/software-downloads/particularly if you are working with bacterial modifications?

      Thank you!

      I am working on bacterial modifications.
      I know that SMRT tools can be used to analysis epigenetics and I find the protocol here.
      GitHub is where people build software. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects.


      But the examples used in the protocol are based on visualized SMRT tools, I am trying to run those data on linux platform so command lines are required. I have already aligned the h5 to reference genome using pbalign, but the following steps are not the clear to me.

        It is not straightforward to run the analysis outside of a SMRT Analysis pipeline. SMRT Analysis can be installed on linux, and the analysis carried out via the command line
        Code:
        smrtpipe.py --examples
        or web interface. If you are having problems installing SMRT Analysis, it can be used via an Amazon ami https://github.com/PacificBioscience...MRT-Portal-AMI, or virtual machine https://github.com/PacificBioscience...achine-Install

          When I tried to test with smrtpipe.py --example, I found that the python module "SMRTpipe" was missing. After I installed SMRT analysis tools, I found a lot of similar modules missing and I had to install them when I noticed that one was missing. Why is this happening? Do I misinstall it at the very beginning?

            Did you follow the install guide?

              Yes, I followed it. But I guess it's the problem that I don't have root access and I solved these by installing some packages with my local python.

                Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
                by SEQadmin2



                Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

                Cancer Drug Resistance: The Lingering Barrier to Rising Survival
                by SEQadmin2



                Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

                There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

                Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
