First, we improved rendering performance for quantitative tracks. In our tests, Persephone shows 10 tracks, each containing 10 subtracks combined via Multi-trace mode without a noticeable delay! In addition, we’ve expanded the controls available for rendering quantitative tracks (typically bedGraph or...
When multiple maps are displayed with thousands of connectors linking shared features, it can be difficult to trace which regions correspond to a specific interval. The new version of Persephone introduces connector filtering, allowing you to hide all links except...
If you haven’t noticed, we’ve added a new view of the synteny matrix that arranges all maps from both genomes in two parallel rows. In many cases, this layout highlights structural variations—such as inter‑chromosomal translocations—more clearly than the traditional matrix. When...
To facilitate the quick export of gene information, including exon/intron structure, we added a new tab to the gene properties form. It displays text in GFF format that "spells out" exon and CDS coordinates. Now, you can copy the gene...
A long‑requested improvement is now here: tracks can finally be moved directly on the map. In addition to reordering tracks through the track panel, you can now reposition any track simply by dragging its label. This provides the most natural...
The latest addition to Persephone’s toolset is an interactive interface for editing gene models. When you encounter an issue in an existing gene model, you can now create your own corrected version of the gene structure and save it so...
The Persephone version, published recently, presents a few improvements. Handling BCF Files In addition to VCF, Persephone now directly supports BCF files imported into the main application. Users can add variants by referencing remote BCF files (with an index) or by loading...
Synteny regions between maps are revealed by linking orthologous genes or common markers. Now you can export these pairs by clicking the button Export visible data in Synteny matrix form. Select two genomes, optionally zoom in on a region of...
Updated: added batch processing If you design an assay targeting a specific allele, it is important to know the genomic sequence neighborhood. A new addition to the Local variants interface will allow users to export flanking sequences around the selected variant....
The data for variants loaded from a VCF file can contain sequencing coverage depth (the DP tag in the INFO field). We now allow the automated creation of a quantitative track that stores these DP values. This feature will work...
