  • alignement paired end reads to long reads

    Hello,
    I have a paired end reads DNA from illumina. and I want to make an alignment of paired end reads on PacBio long reads.
    how to do this alignment?
    I know that there are alignment tools that can do this job but I want to try to create an alignment tool like this.
    the problem is I have one Long reads file but I have two paired end reads file.
    how to align the paired end reads on long reads? do I have to take foward.fq and reverse.fq (paired end) separetly?
    Thank you

      Take a fasta representation of the PacBio reads (there is nothing special about PacBio sequence). Use any NGS aligner of your choice after constructing a suitable index providing the PE data files. NGS aligners are aware that the PE reads are sequences from two ends of the same fragment.

        Thank you for your answer.
        I know that there are aligners NGS that can do this job but I want to understand the principle of alignment of paired end to a long sequence reads as PacBio.
        if for example I want to create an alignment tools.
        My question is not found in the articles of NGS alignments programs.
        This is why I know how it works.

            Thank you for the links.
            But none of the links does not answer my question.
            I know the stages of alignment and I aligement process.
            for example in the alignment sequences used to align sequence to another sequence.
            But in case of paired end, we have three sequences: paired end (2 sequences) and another sequnce! we try to align paired end reads to the sequence(consensus for example or the long reads)!
            how to do this ?? !!
            My question is not found in either the articles.
            can you help me?

              I don't think we are going to solve this through a forum discussion such as this. You need to find a sequencing facility (and/or a computational biologist/bioinformaticist) at your institute/university and talk through your doubts with them in person.

                Genomax thank you for your help.
                You have helped me a lot.
                Is there another person who knows the answer?

                  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...
