    The other option is to hunt for a working ACE to SAM/BAM converter which handles the paired information - people have tried this before but I'm not sure if there is a complete solution.

    There are quite a few options to "optimize" this process ... but it's always a problem, when there is no time and things just "need to get done"..

    But I agree, .. with MIRA4 you gain more flexibilty. E.g. Staden's gap4/5 :-)

    Also Newbler had some experimental BAM output support - I'm not sure if it was ever properly finished and working though.
    hey, thanks. yes I thought I'd need to convert it but that prob means doing the assembly again and I'll have to fish out the paired and unpaired reads (mixed in the. sff) But I'll get around to it.
    Thanks for the advice.

    Thanks Sven, I followed the consed docs on installation and wasted a day in the attempt.. error after error.. so don't have time for it. Need results. I'll try the other progs.
    Thx again.

    If you want to edit the assembly (e.g. move contigs around etc.) I'd recommend consed. Installation is not really complicated and very well documented. Newbler, gsAssembler, is able to produce a complete consed folder. This has to be checked before the actual (denovo) assembly.

    If it is just for viewing the paired reads information / contig layout, Hawkeye is the way to go :-)

    my 2p,
    Sven

    Hi,

    I tried Eagle, Consed (couldn't install), Tablet, Magicviewer. Tablet does show the orietation of each paired read.. The more I think about it, that should be enough, but it would be nice to view the 'joined' contigs together. I will try amos.

    Thanks,

    S.

    What viewers have you tried?

    Have you tried Hawkeye, it is part of the Amos package?

  • 454 ACE assembly with paired reads... how to view?

    Hi,

    I'm new here, thanks in advance for any help.

    I have a 454 dataset of 'allcontigs.ace'. The reads consist of paired and unpaired. If I use a viewer like Tablet, which I find very good.. I can see the paired reads in the contigs and which other contigs they are paired to etc. but I cannot see the corresponding orientation of those contigs.. I should say, I am trying to examine a 'chain' of contigs out from one of interest, none of which have been included in the scaffold (because they originate from a 16S sequence). So my question is.. is there a viewer I can use which will show the contigs and their relative orientation, based on the paired reads they share?

    I have tried several so far with no luck.

    Thanks very much,

    S.

    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.”
