  • which is the right conversion for Solid?

    Hi, I have been using several scripts from maq, fastq-mcf and galaxy to transform my csfasta & qual data into fastq (in base space). all of them gave me the same sequence, but when I tried to do it manually based on the code given by Solid I get a different sequence. I tried a script that I found in a forum and is the only script that has coincide with my translation. Can anyone tell me which is the right conversion and which one has a frame shift please?

    The csfasta to fastq converters will not decode the sequence to basespace. The manual way is the correct conversion, but it is likely not the correct sequence given the high error rate.

      Thanks Chiper, I am also filtering the low quality bases on both extremes and removing all the reads with non-called bases

        Recent Advances in Sequencing Analysis Tools
        by seqadmin


        The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

        Essential Discoveries and Tools in Epitranscriptomics
        by seqadmin




        The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
