  • alignment software and ref sequence

    We are currently using MAQ to align our Solexa reads to our reference sequence. Does anyone know if MAQ can also tell me which parts of my reference sequence have no reads aligned to them? If not, can anyone suggest a program that can tell me this info? Thanks!

    Pretty sure MAQ can't, and a quick scan of the man page didn't yield anything.

    Have you tried one of the visualization tools? Only one I know off the top of my head is tablet, but unfortunately haven't had a chance to play with it myself:

      Actually, if I am not wrong, Maq`s pileup output has a column with the number of reads aligning at a given position, so you can get those with a 0 coverage out

      HTH,

        MIRA does. Can even give back a list of genes and/or intergenic regions which are hit by this (if references sequence has annotations like, e.g., a GenBank). If you're working with 20 to 30m reads, have a look at it.

        Beware, being a de-novo assembler, it's a lot more memory intensive than other mapping programs when used for mapping only.

        Disclaimer: I wrote MIRA. It's useful to me but it might not be for you. Feedback appreciated.

          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...
