1. Whole-sequence visualization
The whole-sequence visualization image is started at the point of maximum GC disparity. The image includes the GC disparity curve and the K-mer cumulative score graph, and marks the locations of replication origin proteins and replication origins with red and green rectangles, respectively. Users can zoom in and out of the image by scrolling the mouse wheel or select and view specific datasets of interest by clicking on the legend above.
2. Replication origin visualization
The replication origin visualization module further displays the locations, level, and supporting evidence of replication origins through both Z’ curve and smoothed Z’ curve, with AT-rich and GC-rich regions marked in pink and green, respectively. This module also includes a sequence schematic that illustrates the distribution of motifs and potential iterons or RNA primers, providing a comprehensive overview of the replication initiation landscape.
3. Replication initiation protein information
The detailed replication initiation protein information module includes the MMseq alignment results between the hypothetical replication initiation protein and the seed protein, as well as the conserved domain features of the replication origin protein. In the HTML table, users can click on amino acids to expand the full protein sequence and use the copy button to easily copy the protein sequence for further analysis. In the domain visualization section, hovering the mouse over a specific domain will display detailed information about that domain.

4. Integrated SeqViz
This module visualizes plasmid in both circular and linear formats. RIP proteins are marked in red, OriV in green, hypothetical proteins in gray, Other CDS in blue, and ncRNA & Regulatory RNA in yellow. Users can easily view the distribution characteristics of replication origin proteins and replication origins. Additionally, the replication origin section provides detailed annotations of potential iterons, DnaA Boxes, AT-rich regions, and conserved site information related to the replication origins of different plasmid types. Users can simply select a sequence and press CTRL+C (Windows) to copy the corresponding sequence for further analysis.
