  • Mapping cDNA's to assembly

    I've got a partial assembly of a low coverage genome (about 250k contigs) and a set of assembled cDNAs I'd like to map to those contigs to get a first guess as to where the introns lie, etc-. Is there a nice piece of software that'll do that relatively quickly? I suppose I could do it with several rounds of blast, or even script a pipeline that makes a blast DB from each assembled genome contig and runs the cnda against it, but I figured I'd ask here first. Visualization would also be a nice plus...

    Thanks!

    Blast would be an option and you can then use the script blast2sam.pl from samtools to get the sam version and vizualise with IGV

      I find BLAT has a better understanding of spliced alignments

      I use Don Gilbert's blat2gff.pl and view in gbrowse

        Don't know if it's relevent but I just read the BWA for long read paper. you could have a look at that

          mgalign also has a much better understanding of spliced alignments than BLAST.

          I used this to annotate a velvet assembly and was quite pleased at the results. The output is easily translated to genepred or bed formats.

            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...

            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...
