  • Maize Endopserm RNAseq: Cufflinks

    Hello
    I have performed maize endosperm RNA seq. I have a total of 48 seq reads (24 samples at two lanes each) to cover. These are all GAII reads. I am mailing because I am confused about Cufflinks input.

    I built a bowtie index of the maize genome. I then ran Tophat, for which I used the index as the reference and supplied four (two samples x two lanes) of my sequences from a flow cell. I got the desired output, accepted_hits.sam. This describes every hit to each of the sequences that I supplied. Now can I use this combined (all four reads against the maize genome) accepted_hits.sam input for Cufflinks? Should I have run Tophat on each 'sequence read' separately, or is there a way Cufflinks parses the tophat output (accepted_hits.sam) for each read?

    Any suggestions?

    thanks

    Tophat should be run for each sample separately, cufflinks is also run for each sample separately. Then cuffcompare is run on all samples at once, and used to track Cufflinks transcripts across multiple experiments and, optionally, compare the assembled transcripts to a reference annotation.

    Hope this helps.

      Thanks a lot Boel. I will run them separately for each sample.

        The Impact of AI in Genomic Medicine
        by seqadmin



        Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

        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.”
