We’ve introduced a new video tutorial showcasing the multi-map mode, designed to provide a compact and intuitive view of multiple syntenic maps. To get started, simply open a blank screen via Tools → Multimap and select a main reference map. The...
It might look simple - to change straight connecting lines to curvy splines - but using standard graphics libraries to draw thousands of Bezier curves will not provide adequate rendering speeds. We had to delve deeply into the GPU shader...
As you probably noticed, when the Persephone's stage is empty, we show a graphical representation of the selected genome. We made the overview of the maps more informative by adding the sequence histograms. They are based on the GC content...
We have loaded 23 genomes of the genus Solanum from the project described at Solgenomics.net. The set includes species such as bitter tomato, African eggplant, melon-pear, and others. They can be opened in Persephone by following these direct links: Solanum abutiloides...
An Italian ryegrass (Lolium multiflorum) cultivar Rabiosa genome has been loaded to the system. The other ryegrass genomes can be linked by orthologous gene pairs. Use the Multimap tool to align individual maps. Open the list of Italian ryegrass maps by...
It was a pleasure collaborating with scientists from KAUST, INRAE, and other institutions on our recent publication in Nature, titled "Genome assembly of a diversity panel of Chenopodium quinoa." As part of this collaboration, we uploaded nine quinoa genomes to...
A small addition to the coffee pangenome data set: Coffea arabica var. Geisha. Chromosomes of C.arabica Geisha and Cara_1.0 are aligned using minimap2 Here is the direct link to this screen in Persephone: https://web.persephonesoft.com/?bookmark=B71E475989EAFC13B9D9E68A8FE6ACC9 The genome of Geisha variety was downloaded from Phytozome....
Happy New Year, All! We are going to the Plant and Animal Genome conference in San Diego. There, we will present our latest version of Persephone. It includes new features that make navigating pangenomes easier.We are introducing the redesigned Synteny matrix,...
We keep adding new features to Persephone. In the Summer Update, we introduced DNA motif search and the tools for analysis of variation in a given genomic region. DNA motif search This feature has been designed to help answer challenging questions...
We have added a new set of SNPs for the wheat genome (IWGSC v2.1). The VCF file with the variants (ExomeCapture) was downloaded from https://zenodo.org/records/7852690. According to the description of the dataset at Variations - WHEAT URGI (inra.fr), "VCF file of 2,799,166...
