  • using data from multiple platforms/technologies

    Hi all - I have a few data sets (assembled sequences), which were generated using a few technologies - Sanger, Illumina (assembled with trinity), 454 (assembled with iAssembler, or in another way with mira and cap3). I would like to use all these datasets for a comparative analysis. My analysis requires that I minimize the amount of redundancies in each data set - that is, I prefer to have alternative splice variants clustered together, and choose a consensus for all of the together, rather than to have them separated.
    I would highly appreciate any suggestions. Currently, I am thinking about running CAP3 on each assembled data set one time, in order to reduce redundancy and also homogenize the data a bit. I am new to all this thought, so I am not sure if this is the best options. I did compare cap3 and cdhit on artifical splice variants that I created - and reached the conclusion that cap3 is better for this job.
    Thank you in advance for your help

    I use `usearch cluster_smallmem` to reduce redundancy. It's similar to CDHIT, but much faster. CAP3 can be useful for creating superassemblies to merge different assemblies together, but it's so slow that I wouldn't want to have to run it many times.

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
