Both reference assemblies were just our PacBio data. Jupyter notebook (GitHub): [20171005_docker_oly_redundans.ipynb](https://github.com/sr320/LabDocs/blob/master/jupyter_nbs/sam/20171005_docker_oly_redundans.ipynb) Notebook is also embedded at the end of this post. * Redundans/Canu assembly (scaffolded assembly; FASTA): [https://owl.fish.washington.edu/Athaliana/20171004_redundans/scaffolds.reduced.fa](http://owl.fish.washington.edu/Athaliana/20171004_redundans/scaffolds.reduced.fa) * Racon PacBio assembly (contigs: FASTA): [https://owl.fish.washington.edu/Athaliana/201709_oly_pacbio_assembly_minimap_asm_racon/20170918_oly_pacbio_racon1_consensus.fasta](http://owl.fish.washington.edu/Athaliana/201709_oly_pacbio_assembly_minimap_asm_racon/20170918_oly_pacbio_racon1_consensus.fasta) Results: * Redundans/Racon Output folder: [https://owl.fish.washington.edu/Athaliana/20171005_redundans/](http://owl.fish.washington.edu/Athaliana/20171005_redundans/) * Redundans/Racon assembly (scaffolded assembly; FASTA): [https://owl.fish.washington.edu/Athaliana/20171005_redundans/scaffolds.reduced.fa](http://owl.fish.washington.edu/Athaliana/20171005_redundans/scaffolds.reduced.fa) * QUAST output folder (default settings): [https://owl.fish.washington.edu/Athaliana/quast_results/results_2017_10_06_22_21_06/](http://owl.fish.washington.edu/Athaliana/quast_results/results_2017_10_06_22_21_06/) * QUAST output folder (--scaffolds setting): [https://owl.fish.washington.edu/Athaliana/quast_results/results_2017_10_06_22_27_26/](http://owl.fish.washington.edu/Athaliana/quast_results/results_2017_10_06_22_27_26/) It should be noted that the paired reads for each of the BGI mate-pair Illumina data did not assemble, [just like last time I used them](https://robertslab.github.io/sams-notebook/posts/2017/2017-10-05-genome-assembly-olympia-oyster-redundans-with-illumina-pacbio/): * 160103_I137_FCH3V5YBBXX_L3_WHOSTibkDCABDLAAPEI-62_2.fq.gz * 160103_I137_FCH3V5YBBXX_L3_WHOSTibkDCACDTAAPEI-75_2.fq.gz * 160103_I137_FCH3V5YBBXX_L4_WHOSTibkDCABDLAAPEI-62_2.fq.gz * 160103_I137_FCH3V5YBBXX_L4_WHOSTibkDCACDTAAPEI-75_2.fq.gz * 160103_I137_FCH3V5YBBXX_L5_WHOSTibkDCAADWAAPEI-74_2.fq.gz * 160103_I137_FCH3V5YBBXX_L6_WHOSTibkDCAADWAAPEI-74_2.fq.gz Redundans with Canu is better, suggesting that the Canu assembly is the better of the two PacBio assemblies (which we had already suspected).
