Extreme environments present profound physiological stress. The adaptation of closely related species to these environments is likely to invoke congruent genetic responses resulting in similar physiological and/or morphological adaptations, a process termed “parallel evolution” (1). Existing evidence shows that parallel evolution is more common at the phenotypic level than at…

One-hot encoding for PLINK or VCF 0 I want to write an autoencoder for SNP data. Is there an established way to one-hot-encode binary PLINK or VCF input? I believe that can be done by manipulating PLINK’s bed file but am afraid to do something wrong. By one-hot encoding I…

This repository includes a python implemenation of Gnomix, a fast and accurate local ancestry method. Gnomix can be used in two ways: training a model from scratch using reference training data or loading a pre-trained Gnomix model (see Pre-Trained Models below) In both cases the models are used to infer…

Global phylogenetic analysis A Maximum Likelihood (ML) phylogenetic tree based on the 69 M. bovis isolates and reference genome was obtained (Fig. 2A). This strategy allows the generation of a more robust tree, when comparing with single gene based trees or multi-locus based trees, that do not capture the variability across the…

Problem with viewing BAM files in IGV 1 Hi everyone, I’m quite new to bioinformatics and I’m having some beginner problems with IGV. I’ve got some BAM files that were generated using the GATK best practice pipeline for SNP discovery, with BAI files located in the same directory. I’m using…

Convert SNP IDs as chr:pos:effect allele:ref allele to rsIDs 0 I have a set of 58000 SNPs for which the SNP ID is in the format of: chr:pos:effect allele:ref allele (Grch37 build), but I need to convert this to rsID where one is available for the SNP. I’ve tried using…

Hi all, I have a vcf file that was extracted from UKB data using qctool (v2.0.6-Ubuntu16.04-x86_64) and contains data in the GP format. This contains a bunch of SNPs from a single chromosome. ❱ wc -l chromosome1.vcf 260 chromosome1.vcf Then I try to convert this file to .bgen again using…
