De novo assembly
Dear all,
Please let me know if I could use CLC Genomic Workbench 8.0 for De novo metagenomic assembly.
Thanks you all so much.

Ask CLC, it's a commercial product, they'll answer your phone call.
I will try, thank you so much.
You will need a license for the microbial genomics module for CLC which requires a separate license. Check with CLC support.
If you're looking for an alternative, a common assembler is Canu. Not sure what type of reads you have though.
Some information about my project: We aim to investigate diversity of microbial community in forest soil. In addition, we also focus on mining genes encoding laccase enzyme.
I sent my DNA samples to Baseclear company (in Netherlands). After that they gave me paired-end raw sequences and assembled sequence that was assembled using CLC Genomic Workench 8.0. I don't know that this Workbench was optimized for metagenomic de novo assembly. Is this method good enough for downstream bioinformatics analysis?
Thank you all for your help!
I am not sure you can use canu in this case.
You may want to try SPAdes or metavelvet. Both will require knowledge of unix/command line along with access to a proper server with enough RAM etc.
Right, illumina sequencing. You're right and Canu is not appropriate here. Just back from London Calling (Oxford Nanopore Conference) :-)
Thanks but what do you think about CLC Genomic workbench? Is it appropriate? I have already received assembled results from Baseclear and I am confusing about this results.
I don't know if there is a difference between the CLC genome assembler (and the one provided by CLC microbial genomics module). You are going to have to contact Baseclear and ask them which one they used for the assembly. Then call/email CLC tech support and ask them about difference, in case Baseclear did not use the microbial one. If they say that there are no differences then you should be able to go ahead with whatever else you want to do with this assembly.
If you want to start from scratch with fastq reads, we have given you a couple of options above.
Thanks so much for your suggestions.
