A visualization session can be launched from the search results table within the Vault, after Visualization is activated by a CDD administrator. Contact us if you'd like to try Visualization for yourself.
Sending search results from Vault to Vision
Since the Vision session draws the input data from CDD Vault, you will need to configure the search results table in the Vault with all of the results you wish to pass to Vision. Here's a refresher on how to customize your report to adjust the data in the results table.
Numeric data, such as aggregate readouts from protocols, as well as chemical properties can be included in a Vision session. At least one numeric data series must be present in the search results in order to launch a Vision session. While you will be able to visualize up to 4 data series at a time in a single scatter plot.
Note: Vision is limited to 1000 molecules and about 30 numeric columns from your Report Table. If you go over these limits, the Vision window will appear blank.
Numeric chemical properties will be passed as is to the Vision session without any modifications. Make sure to select chemical properties under customize your report in the Vault prior to sending the data to Vision.
Protocol readout data
The protocol data in Vision is always aggregated at the molecule/protocol level, which is an important distinction from the Vault search results table, where you can display replicate data points per molecule. This means that any results passed from CDD Vault will be averaged across all runs and across batches, to yield a single value per molecule. With a notable exception of end-point readouts in a protocol with conditions, aggregation will be automatically performed by Vision.
|Readout type||Protocol with conditions||Protocol without conditions|
|Readout marked as condition||
(plain readout definition)
|Normalized against controls||
Example 1: If your search results table in the Vault includes multiple IC50 values per molecule, and the protocol does not have any conditions, you will see a single IC50 geometric average within the Vision session.
Example 2: If the search results table in the Vault includes IC50s under several conditions, you will see a separate IC50 geometric average for each condition.
Example 3: if your search results table in the Vault contains a dose-response set, including concentrations, inhibitions and IC50ss, you will see a single IC50 value per molecule in the Vision session, while concentrations and inhibitions will not be included.
Navigating the Vision work space
At least one numeric data series must be present in the search results for the "Launch Vision" icon to light up.
Once you have a set of results loaded on the Explore Data -> Search page, you will see the "Launch Vision" icon prominently in the search results table header.
The session is launched in a new window with a default view that includes a scatter plot, a data table, and a set of actions and controls.
For the best experience, please use the latest version of Chrome browser.
The most prominent part of the work space is the 4-dimensional scatter plot. Click on the "expand" icon in the top right corner to maximize the plot.
X and Y Axes
By default, the initial plot is a two-dimensional plot of the first two columns of the data table on the X and Y axes, with the same series used for color-coding and the size of the points.
- Select the data series you wish to plot on the X and Y axes. The plot will adjust dynamically.
Color and Size mapping
- Click on the icon, or on the color/size legend under the plot, to change the data-series used for color and size mapping of the points.
- Select the data-series to be used for color-mapping from the drop-down. Slide the end-points of the color-wheel to adjust the range of colors. The mouse pointer will show the low and high values of the spectrum.
- Select the data-series for point size mapping in ascending or descending order.
Plot Zoom and point selection
- Click and drag the mouse over a selection of point to zoom in on that area of the plot. The plot area will resize dynamically, and you will see the number of selected molecules update in the top right corner of the plot, and filter histograms will update to reflect plot selection.
- Double click in the empty plot area to reset zoom. Also, reset using "Undo" and "Reset" links at the top of the Vision window.
Each point on the plot represents data from a single molecule. Recall that protocol data is aggregated per molecule.
- Molecules that are missing data in the plotted series will be omitted. You will see a warning message below the plot.
- Mouse over a data point to see a preview of the molecule structure.
- Click on a data point to see detailed data for the molecule. Click outside of the pop-up to close it. Click on the molecule name in the pop-up to go to the complete molecule record in CDD Vault.
Underneath the scatter plot, you find a dynamic data table containing the molecule structures and all of the numeric data. This table is similar to the search results table in CDD Vault.
- Click on the "expand" icon to see the full table.
- The table dynamically updates to reflect the molecule selection in the scatter-plot. For example, if you zoom in on 13 molecules in the plot, the table will show 13 molecule out of the originally loaded set. Resetting the plot will reset the table.
- The check-boxes along the molecules let you cherry-pick further. All molecules are selected by default, and when you de-select a molecule, the corresponding point on the scatter-plot is greyed out, and the count is updated.
Controls and Actions
Along the right side of the work space runs a section with controls and actions. There are 3 tabs in this section.
- Filters allow you to select a sub-set of molecules based on filter criteria
- Plots currently allows you to export the scatter plots. As Vision matures, this section will incorporate additional plot types.
- Session allows you to save the active Vision session, and to share it with other members of your CDD Vault.
The default tab is "Filters", with 4 filters pre-loaded at the start of the session.
- Each filter is a frequency histogram showing the distribution of the data series. The filter scale ranges from minimum to maximum values of the data series. The height of the bar is determined by the relative frequency of values in that interval.
- Close a filter using the "x" icon in the corner. Add a new filter to the list from the "Add a filter" drop-down.
- Click and drag around a section of the histogram to select the desired range of data. The scatter-plot will dynamically update all of the plotted data-series based on the filter. The filtering parameter may be one of the plotted series, or another data series. For example, filter out molecules with the logP from 1 to 3 (while displaying protocol data on the scatter plot):
- Place the cursor over the selection, and move the entire selected frame to a different range. Place the cursor at the edge of the selection, and drag to contract or expand the frame.
- Reset filter by double-clicking outside of the histogram, in an unselected area.
- Filter data by multiple parameters. When you make a selection on a second filter, the filtering is applied to the previously selected sub-set of molecule. For example filtering 100 molecule by logP 1-3 yielded 78 out of 100 total molecules. Adding a molecular weight filter resultw in 40 molecules from the 78 previously selected.
The plots tab currently contains an export link for the scatter-plot. Future releases of Vision (throughout 2015) will include additional visualization types on the Plots tab, with the ability to configure multiple plots per single Vision session.
- Export scatter-plot to a PDF file. You have an option to change the default axes labels prior to export: just start typing new text in the fields- this will over-ride the default.
The session is tab is still under construction. Future releases of Vision (throughout 2015) will include options to save a dynamic session, and to share the session with Vault members.
A set of molecules identified during analysis in the Vision session can be sent back to CDD Vault. Click on the icon to save selected molecules as a collection.
