    Yep, the same I heard from author

    UCSC recognizes nothing but chr#, so have to you build your own indexes on chromosome sequences, which can downloaded from UCSC.

    I had the same problem before. What you need to do is to make your own bowtie index file using 'bowtie-build' command on fa files you downloaded from UCSC site.

    Hope it helps,

    started a topic TopHat: output is not recognized by UCSC

    TopHat: output is not recognized by UCSC

    Hi, we ran TopHat without a GFF3 file and the output does not appear to be recognizable wiggle and bed formats. Here is what we got (first lines) of the wiggle file:
    track type=bedGraph name="TopHat - read coverage"
    gi|149258597|ref|NT_039457.7|Mm8_39497_37 0 46627 0
    gi|149258597|ref|NT_039457.7|Mm8_39497_37 46627 46667 1
    gi|149258597|ref|NT_039457.7|Mm8_39497_37 46667 48587 0
    gi|149258597|ref|NT_039457.7|Mm8_39497_37 48587 48627 1

    And here is what we got from the bed file:
    track name=junctions description="TopHat junctions"
    gi|149258597|ref|NT_039457.7|Mm8_39497_37 1132498 1133665 JUNC00000001
    13 + 1132498 1133665 255,0,0 2 31,21 0,1146
    gi|149258597|ref|NT_039457.7|Mm8_39497_37 1264693 1270688 JUNC00000002
    39 + 1264693 1270688 255,0,0 2 32,32 0,5963

    The program ran without errors. We think that there is a step missing that would associate the gi/NTs to chromosome coordinates. We are thus wondering what will be the way to work through this.. Is it because of the missing GFF3 file? (we could not find one for mouse, and if this is a problem, we would appreciate some pointers on how to make one) Any other suggestions?

    Thanks very much in advance!

    Exploring the Dynamics of the Tumor Microenvironment
    by seqadmin




    The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

    Exploring Human Diversity Through Large-Scale Omics
    by seqadmin


    In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
