    tools for assembling large contigs

    I need a tool to assemble very large reads.

    I have 2 sets of large contigs, from 454 and Pacbio. The largest contig is 20kb. The average length is 4kb. I'm trying to use those 2 sets of contigs in order to assemble to larger contigs.

    (The clone is about 150kb. )

    Have a look at minimus2, it has been working well for me. You might also want to read about MSR-CA, which is an assembly pipeline that first constructs very long "super-reads" from sequence reads. Then, overlaps between the super-reads are computed, and you might find that there is a way to incorporate your contigs at this stage.

      The latest version of Celera apparently can accepts reads as large as 32 kb for assembly

        Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

        Nine Things a Sample Prep Scientist Thinks About Before Sequencing

        I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

        Here are nine questions we think about, in roughly the order they matter, before...
