    It is not possible to assemble 1x coverage data, because no read will overlap any other read.

      and to add to Torst, most de novo assemblers will have significant problems until you sequence to between 10X and 20X coverage at a minimum.

        Some reads will be overlapping.

        About one third locations have 0x coverage, one third 1x, fewer 2x, even fewer 3x ...

          This is simply not enough coverage. You might be able to detect some SNPs, and assembled a few short regions, but that's it. Sorry.

            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...
