  • View TopHat output

    I want to get alternative splicing in the organism which I was researched,I have the genome sequences(it is unpublished) and RNA-Seq data ,I have use TopHat and get some output files(.bam , .bed files),but I don't know how to see the results,If I want to get the alternative splicing,what should I do ? I have read the TopHat manual and it said that I should use IGV,IGB or UCSC Genome Browser to see the result,I have downloaded IGV,what was the file I should import to IGV,genome sequence or the genome annotation file? and which is the output file I should import?Does anyone can help me ?

    I have the same question. Got the results, but don't understand what is going on...

      I have solved the problem. You can use the IGV to view the result,the TopHat output file .bam file is the reads mapping file,if you import this file to the IGV,you can see how the reads was mapping to the genome sequence,but before you import the .bam file to the IGV,you should use SAMtools command ‘index' to index it.The .bed file is the junction file,you can see the splice site in the IGV after you import the file to it directly.You can see how to use the IGV in its website,and you will see how to see the junction information.

        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...

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
