October 2023: 1,000 wheat exome SNP data as a track on the IWGSC Chinese Spring RefSeq v2.1 genome browser
1,000 wheat exome SNP data were created as a track on the IWGSC Chinese Spring RefSeq v2.1 genome browser based on the Vasudevan and Cloutier, BMC Research Notes, 2023. Press here to see the track on the IWGSC Chinese Spring RefSeq v2.1 genome browser. Excerpts from the abstract:The 1,000 wheat…
Op-ed | Space Force launch strategy a step in the right direction
The Space Force next year will select launch providers for Phase 3 of the National Security Space Launch (NSSL) program. Industry proposals are due Dec. 15. This next phase of NSSL marks a significant evolution in how the Space Force approaches launch, leaning into the commercial market in a way…

Lifting of the 1,000 wheat exome project SNPs from Triticum aestivum cv. Chinese Spring assembly RefSeq v1.0 to RefSeq v2.1
Abstract Objective The 1,000 wheat exome project captured the single nucleotide variants in the coding regions of a diverse set of 890 wheat accessions to analyse the contribution of introgression to adaptation of wheat. However, this highly useful single nucleotide polymorphism (SNP) dataset is based on RefSeq v1.0 of the…

A pangenome reference of 36 Chinese populations
Populations and samples For Phase I of the CPC project, we selected 68 samples from 731 individuals with genomes deep-sequenced using next-generation sequencing. Following a previous study5, we applied a procedure to quantitatively evaluate the genetic diversity coverage based on principal component analysis results. We selected individuals using a statistic…

Repeat masking for genome annotation
Repeat masking for genome annotation 0 I am working on a (plant) genome annotation pipeline and would like some advice regarding repeat masking. My pipeline consists of running several ab-initio gene prediction tools (Augustus, GlimmerHMM and SNAP) + transcript alignment (PASA) + protein alignment (genomeThreader) evidence + gene liftover (liftoff),…

snpeff : wont recognize the gtf or gff3 files (runtime exception) 1 Hi, I am trying to build a custom databasee for snpeff. As instructed both in the forum and snpeff instructions, I did the following; Then I added the following into snpEff.config file # BG94_1 BG94_1.genome : BG94_1 Then…
Are there any alternatives to Liftoff
Are there any alternatives to Liftoff – Mapping annotations (GFF/GTF) between assemblies 2 Hi, I am annotating closely related accession (varieties) using reference assembly (please note that I am using only a region, so that is the reason why you don’t see chromosome info). I really liked liftoff (ver 1.6.1:…

local variable ‘feature_db’ referenced before assignment
Hi, I want to map annotations from rich gencode human gtf or gff3 to great apes’ genome. I tried to run liftoff (github.com/agshumate/Liftoff) but it returns error the below. Following the github issue’s post, I confirmed there’s no _db file before running, the annotation file is .gff3, the permission of…
