EcoSNP-VISTA can be executed on any Windows Linux or MacOS X computer with installed Java version 1.4 or higher.
Follow these instructions to install Java on your machine:
Windows |
Linux |
Solaris
Macintosh users should upgrade their OS to 10.1 or better. Additional java upgrades may be available from Apple's download page.
| File | status | description |
|---|---|---|
| BLAST | mandatory | BLAST output file is used as an input file for the SNPvista program. Distributive package contains an example file Results.cgi.txt |
| Recombinational points | optional | This text format file contains a list of recombination points. Each line of this file contains read name followed by coordinate of recombination point in query coordinates. See example file for details |
| annotation | optional | This text format file contains annotation. Each line of the file contains description of one annotated region and consists of three fields separates by space: annotation_type start_pos_on_query end_pos_on_query. See example file for details |
The distributive package contains some example files. The start.bat will rum SNPvista with these input files: -f Results.cgi.txt -a annot.txt -b breakpoints.txt and a user can edit the start.bat file by using the right button of the mouse and replace the name of the files by yours. If program will found that some mandatory files were omitted it will open a Wizard window so you can open necessary files at program startup. See Usage section for details.

Control Panel contains the following text fields:
|
The top panel of the program shows annotated regions, SNP density, recombination points relatively to the QUERY sequences coordinates. Small red rectangle shows current position relative the whole query length. You can drag this rectangle by mouse to change current position or drag left or right rectangle borders to change start or end position respectively. Small red triangles show all recombination points for the selected read panel.
Tree panel reflects results of clustering procedure. Hamming distance between different sequences is calculated as a relative number of matches of two sequences for each position in the interval. Tree panel is mouse clickable. Each click on small blue rectangles will hide corresponding branch of the tree. Repetitive click in the same rectangle will show hidden branch. After each tree recalculation tree panel will show the whole tree with all branches visible.
Control elements of tree panel are used to enable or disable auto-fit mode and absolute/relative distance mode.
Pressing this button switch between absolute/relative distance modes. In absolute distance mode each branch of the tree has length reflecting real distance between sequences. In relative mode all branches have the same length and tree reflects only relative positions of sequences to each other
If this button is pressed, Tree panel will try to adjust its width to the maximum tree width after all tree recalculation.
Text control contains a scale number. Increasing or decreasing of this number will increase or decrease tree width respectively.
Zoom panel shows positions of recombination points on the zoomed area of the QUERY sequence and points to their positions on the SNP map panel.
Each missmatch between query sequence and other sequences is shown in the SNP panel as a colored square. Color of the square shows exact letter in this position of the sequence. (See legend panel for details)sand-glass sign points to a recombination point near SNP position. Mouse click on any square will show in popup window information about this position and recombination points on the sequence.
Each line of the Data panel contains one sequence in query coordinates. Order of lines is coincided with order of curves in tree and SNP panels. The following color schema is used:
Light green bar - query line
Pink bar - sequence that contains at least one recombination point in the selected interval.
gray bar - sequence contains some recombination points, but they are outside the selected region.
When mouse cursor is moved inside the panel and cross gray or pink bars breakpoint will be shown as red triangles in coordinate rule, even outside selected region.
Position highlighted with green rectangle is a recombination point. When mouse cursor moves above sequences letters red frame highlites corresponding position. Position coordinates are shown in the left gray panelnext to horizontal scrollbar
    |
User can add or remove recombination points by clicking right mouse button when mouse cursor is above the corresponding position. Corresponding popup menu will appear. (see pictures) In Data Panel, if position under the mouse cursor is not marked as a recombination point, "Add Break Point" menu will be shown and this cell will be marked as a recombination point. If position is already marked as a recombination point and has green background of the corresponding cell then "Delete Break Point" menu will appear and this position will be cleared. In SNP Panel new recombination point will be added to a left neighbor position. If interval between this SNP and its nearest left neighbor already contains recombination points, "Delete Break Point" menu will be shown and the nearest recombination point will be removed. |
Status Bar is used to show current status messages and contains progress bar

Recombination points calculator is a front-end shell for the breakpointsCalculator program. In this window the following parameters can be seted up: BreakPoints Calculator: allows change default path to the breakpointsCalculator program. Breakpoints results: User can select name of the file where results of recombination points calculations will be saved. SNP Window: Percent Identity: Min Depth: Window Size: Buttons:Start: starts recombination points calculations. The word "Start" will change to "Stop". Calculation progress will be shown in progress bar. If any new recombination points are found, thew will be shown in the text area. If you want to interrupt calculations - press "Stop" button.Forget: clear list of recombination points. Refresh: refresh the program view. This button can be pressed at any time during calculations, as soon as new recombination points are found. Save: Save the results immediately Close: Close the window. This will not interrupt calculations |
