    Need help in mapping Single end and paired-end reads

    Dear all

    I have in my project single end reads (100 bp) for some samples and paired end reads (100 bp frw and rev) for the other samples. I had to re-sequence some of the samples of which I have paired-end reads because the coverage was to low. However the re-sequence data I received back is single-end reads of 250 bp. Tophat wont allow mapping single and paired-end reads together. It says the result will look bad. They do mention that you can convert the junctions.bed file (output of Tophat) with bed_to_juncs using the -j option. I quote for TopHat manual "run TopHat on the 2nd set of reads using the -j option to supply the junctions file produced by be_to_juncs in the previous step". This is supposed to work but I didn't get it to work. Any suggestion on how I should go about analyzing this data?

    Multiomics Techniques Advancing Disease Research
    by seqadmin


    New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”
