minimap2, before or after assembly?

minimap2, before or after assembly? 1 Dear all, I feel confused because I saw someone uses the minimap2 after demultiplexing, but before proceeding with the assembly (CANU) [case 1], and someone using the minimap2/samfile/BFCTools/medaka after assembly (always CANU) [case 2]. In case 1, the reference file used to align against…

Minimap2 detects too many 16S sequences in metagenome

16S is a very conserved sequence, which is why it’s used for targeted phylogenetic analysis; it makes it easy to amplify and analyse. Unfortunately that conservation is an issue with minimap2, which is built around the idea that matching scattered subsequences within a sequence is good enough for identifying matches…

Pangenome-based genome inference allows efficient and accurate genotyping across a wide spectrum of variant classes

Sequencing data We used publicly available sequencing data from the GIAB consortium45, 1000 Genomes Project high-coverage data46 and Human Genome Structural Variation Consortium (HGSVC)4. All datasets include only samples consented for public dissemination of the full genomes. Statistics and reproducibility For generating the assemblies, we used all 14 samples for…

Mapping back 3 sets of reads/sample with minimap2

I used FaQC to qc my raw fastqs before assembling. That program (and perhaps others) outputs properly paired Forward and Reverse fastqs, as well as an unpaired fastq file for each sample. I used the all 3 for each single sample assembly. Since minimap2 only allows for 2 query files,…

[MonashBioinformaticsPlatform/RSeQC] junction_saturation not suit for bam/sam file generated by minimap or pbmm2

because the CIGAR in bam/sam file generated by minimap2 contain “=” , represent right match with reference, and “X”, represent wrong match with reference. while the bam_cigar.py in ./lib/qcmodule/bam_cigar.py only suit for bam/sam generated such as BWA/bowtie, which CIGAR contain only “M” ,represent mis/match.
