We realized the need to have a specialized page listing the latest changes to our data loader application PersephoneShell. This tool is under active development, as we try to cover more of different data types. The new features of PersephoneShell...
We have added the data for 26 Zea mays reference genomes from the pan-genome project "Whole-Genome Assembly of the maize NAM founders" (https://nam-genomes.org/). The source files were downloaded from MaizeGDB.org. To help browsing this pan-genome data set and provide the...
We are pleased to welcome King Abdullah University of Science and Technology into the growing community of Persephone users. One of the top-ranking institutions, KAUST advances science and technology through distinctive and collaborative research integrated with graduate education. To learn more about our...
According to the publication in Nature (https://www.nature.com/articles/s41591-020-0820-9), the spike protein of SARS-CoV-2 has a polybasic cleavage site due to an insertion of 12 nucleotides at the region encoding the junction of S1 and S2 subunits. "This allows effective cleavage by furin and other...
The newly added feature that allows instant BLASTN comparison of aligned sequences can be applied to an interactive sequence comparison for multiple accessions of the infamous coronavirus COVID-19. We also added bat RaTG13 and bat-SL-CoVZC45 coronaviruses and an older SARS-CoV to the...
We are introducing a new feature that allows to compare nucleotides of aligned maps with one click. First, open two maps to be compared. The lines that connect common markers or homologous genes will help you locate syntenic regions. Zoom...
We rolled out a new version of Web Persephone with major feature upgrade: the users can upload their own tracks, and we made sure that all possible optimizations necessary to achieve maximum performance are in place. The system should handle...
This week's addition is a pair of citrus genomes: C.sinensis (sweet orange) and (pomelo). We uploaded the genomic sequences with annotation tracks to the Desktop and Web versions. As usual, a routine alignment of syntenic chromosomes reveals large structural rearrangements. We...
We continue to support and learn from the largest International Plant and Animal Genome meeting in San Diego CA. Many thanks to all who stopped by our exhibit. This year was special for us because we were able to showcase a...
The update has a few technical improvements that make loading the marker data much faster. This is done by storing and transmitting the markers in specially-compressed binary blobs. The Synteny matrix has now an improved responsiveness, partially due to more efficient...
