Natera has announced the launch of Prospera with quantification, the only cell-free DNA (cfDNA) test for kidney rejection that provides three values—the quantity of donor-derived cfDNA (dd-cfDNA), fraction of dd-cfDNA, and total cfDNA—on every report. Combining these three metrics has been shown to improve sensitivity when evaluating transplant rejection, compared…

Merging genotyping array VCFs and then running kinship analysis 0 Hello, I have about 4200 array genotyping VCFs (from the Illumina Infinium CoreExome-24 Kit) and I have merged them using bcftools merge. The chip has 500K exonic SNPs. These are trio data – which means 1700 of them are probands,…

Annual and perennial species occur in many plant families. Annual plants and some perennials are monocarpic (flowering once in their life cycle), characterized by a massive flowering and typically produce many seeds before the whole plant senesces. By contrast, most perennials live for many years, show delayed reproduction, and are…

Relatedness vs relatedness2 from vcftools give different results 1 Hello All How to you think about this relatedness results?

What is the best QC to do on imputed UK Biobank data? 0 I am receiving imputed data from UK Biobank to conduct a GWAS on. Previously I have carried out GWAS on genotype data, which I have QC’d for missingness per individual and per SNP, sex discrepancy, MAF filter…

Introduction Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogen and the leading cause of healthcare-associated infections.1 Multidrug-resistant (MDR) K. pneumoniae isolates are rapidly spreading, thus limiting the choice of antimicrobial agents for empiric treatment of infections caused by these microorganisms; hence, this is a public health challenge.2 Polymyxins are last-resort…

Can KING relatedness software be set to ignore FID? 0 Hi all, I’m using KING to determine relatedness and duplicated samples in a dataset. The FID column in my fam files has been used for batch IDs, and doesn’t refer to family relatedness at all. Will this have an impact…

Filter duplicate ID from PLINK file 0 Hi All, I am new to SNP-chip data analysis. I have been exploring some SNP-chip data using plink 1.9, while checking the Relatedness using KING, I am getting an error of duplicate ID. I was wondering if there is any method I can…

Introduction Pseudomonas stutzeri is an aerobic, nonfermenting, active, Gram-negative oxidase-positive bacterium with unique colony morphology.1,2 Burri and Stutzer first described it in 1985,3 and the specific metabolic properties, such as denitrification, degradation of aromatic compounds, and nitrogen fixation, distinguish it from other pseudomonads species.2,4 Historically, P. stutzeri was not commonly…

I struggle to infer relationships in a dataset of 20K exomes from tens of kits. At first I found a well-covered union of regions – check. Second, I performed everything to merge 20K VCFs into one. Removed indels and multi-allelic variants. Check. Still, when I run KING with “kinship” option,…
