    I did'nt include the fusion flags and it worked ok. Is anybody seeing any significant speedup compared to 1.4.1? I dont.

    Code:
    time tophat2 -p 8 -r 50 --mate-std-dev 50 --transcriptome-index=./tophat2_transcript/GRCh37_E66 -o ./t2 \
    -n 2 -N 4 --b2-sensitive --library-type fr-unstranded \
    --rg-id ID000 --rg-sample M123 --rg-library lib0000 --rg-platform-unit IlluminaLn7 --rg-center TGen \
    $RESOURCES/bowtie2/GRCh37.62 ./1mr1.fastq ./1mr2.fastq

    Yes, the updated version also solved the problems I was having with crashes and hangs in the 'Joining segment' part of the program. My samples are being mapped to a non-standard organism that has over 80 scaffolds.

If tophat 2 still fails at any stage in the process please report the failure at [email protected] - it would also help if you attach a tarball or zip file with the content of the "logs" directory when you post a bug report there.

    The updated version fixed the error I posted earlier in the thread. Thank you for the quick work!

    I have a simillar problem at the same stage:
    [FAILED]
    Error: segment-based junction search failed with err =-6
    Error: invalid 'B' array subtype (B)!


    and TopHat was run with the following parameters:
    --bowtie1 --report-secondary-alignments --bowtie-n

    Same here. Tophat2 hangs forever at the same step "Searching for junctions via segment mapping", with paired-end HiSeq fastq reads (~140M reads), with or without --fusion-search option.
    I ran it succesfully on a small subset of the same files (1M reads), so I suspect it has to deal with data size / memory...
    Hope for a quick fix!

    yeah, and i also removed fusion detection completely but they all end up giving the same error.

    Have you tried the fusion version with the -bowtie1 option as suggested when you are doing the fusion detection.

    I've had an error pop about at the same point when I gave it a test run the other day myself.
    Was single end mapping.
    Went through the left_kept_reads then:
    [timestamp] Searching for junctions via segment mapping
    [timestamp] Retrieving sequences for splices
    [FAILED]
    Error: Splice sequence retrieval failed with err =-6

    started a topic tophat2 errors

    tophat2 errors

    now that we have tophat2 out the door, i'm sure we'll have bunch of tophat2 related error messages and solutions - hopefully.

    thank you to the team for releasing the new version. i'm very excited for the combination of tophat and tophat-fusion.

    now my problem. I've downloaded and installed bowtie2 and tophat2. everything started out just fine until tophat tried to search for junctions via segment mapping. I got an error 5

    Code:
    tophat2 -o A673_rep1_tophat2 -r 158 --mate-std-dev 44 -p 24 --microexon-search --library-type fr-unstranded --b2-sensitive --fusion-search --fusion-min-dist 50000 --fusion-multireads 5 --fusion-multipairs 5 ~/genome_reference/bowtie_indexed/hg19.bowtie2 A673_rep1_R1.fastq A673_rep1_R2.fastq

    I'm hoping it's an easy solution and am sure it's something i did wrong. anyone has any ideas?

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
