  • Gene fusions/duplications in GRIMM-Synteny?

    I am attempting to look at homologous synteny blocks in an organelle genome across a few different species using GRIMM Synteny.

    Reading the documentation files and Tessler & Bourque (2008), I have understood how to manually code sequence data to a format that GRIMM Synteny can accept (I am using gene coordinates):

    1 1 start_1 length_1 strand_1 1 start_2 length_2 strand_2 etc.

    This works great for most of the genes I am looking at. However, I seem to have gotten stuck in two particular situations: gene fusions and gene duplications (and since it is an organelle, it is a unichromosomal analysis). The typical situation here is that one species has a gene fusion or gene duplication, but another one in the analysis does not.

    Can those genes be used in GRIMM Synteny? If so, in what format should they be written?

    I have performed a forum search, a Google search and a search at Pubmed without any luck so far.

    Thank you for your time, have a nice day.

    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...
