Incremental average and SD by awk. awk '{dx=$1-mx;mx+=dx/NR;dx2=dx*($1-mx)-vx} NR>1{vx+=dx2/(NR-1)} END{print mx,sqrt(vx)}' file Covariance is available by extending this idea. I saw this in Dr. Larry Schaeffer's course note although it should be a well-known method.

Attenting a UPOV UPOV (plant variety protection) meeting in Hangzhou China to learn everything about DUS testing. In the coffee break we do cake testing 😋😀

My Genomic Prediction course is running again in the summer, now back to back with a course on Gene Mapping by Goutam Sahana. The links below lead to pages for master students, but these courses are also open to PhD students and others. QGG AU Aarhus Universitet

Very proud of my PhD student Charlotte who successfully defended her thesis on improving malting quality in winter #barley with Sejet Plant Breeding. Results already in use, #betterbarley for Denmark 🇩🇰🙂. Congratulations dr. Robertsen! QGG AU. phd.tech.au.dk/about-us/curre…

Congratulations Pernille! More #betterbarley (and grass) from QGG AU. I was involved in Pernille's thesis to map markers for root number in #barley, where mixed models failed but Bayesian mapping succeeded 🙂. Hopefully ready to submit soon!

I reviewed a paper where authors had increased their data size by adding genomic predicted phenotypes, and then did GWAS. Don't do it, it is flawed! The predicted phenos are basically copies of the training SNP effects, inflating the test statistics for GWAS. End of review ☹️

Good news from our NORFAB project with Fernando Geu-Flores doing fantastic research resolving the vicine / convicine pathways in faba bean 👍👇

A few weeks left until the application deadline (Sept. 30th) for these fully-funded positions in our group QGG AU: PhD in evolutionary genomics and quantitative genetics, postdoc in machine learning and bioinformatics nature.com/naturecareers/… nature.com/naturecareers/…

Our cool paper on clover genetics with image analysis by machine learning, prediction of synthetics that were actually made and grown to verify and more 👇

We have an available position as professor in Crop Genetics at QGG Flakkebjerg. Deadline 1 July 2022. Read more here: bit.ly/3mzJZ4B Mogens Sandø Lund Luc Janss

Don't know what it is with #plantsvszombies but the course is on #GenomicPrediction in #animals and #plants. The contents have been extended to address kernel methods for GxE and non-additive genetics and again with Guillaume Ramstein on the lecturing team.

With contributions of QGG AU by Elesandro Bornhofen and me and lead author colleague stiguandersen of Molekylærbiologi - Molecular Biology Aarhus Universitet. Great work Murukarthick Jayakodi and other first and co-authors 🤗.

New article out by Elesandro Bornhofen Luc Janss et al: #Genetic architecture of inter-specific and -generic #grass #hybrids by network analysis on #multi-omics #data DLF BMC Series Find the article here bit.ly/42rq5fs

And the faba bean papers keep coming out, this one is from former PhD student Cathrine Skovbjerg 👇

Nice article by Kenny et al. (doi.org/10.1186/s12711…) on the variation in genomic relationships in full sibs. Raw relationships are avg 0.55 up to 0.85, after correcting for parent relationships and inbreeding they are nicely 0.5 with a range 0.4-0.6, as expected by theory🙂👍

PLEASE RT 🌞 QGG's #SummerUniversity courses are online, and you can find an overview here: qgg.au.dk/en/education/s… Deadline for application is 15 March 2024 🌞 Doug Speed Goutam Sahana Guillaume Ramstein Luc Janss
