3.3 Overview of the GS Run Browser Interface
After a sequencing Run data set has been loaded, it will be displayed in the GS Run Browser window (Figure 18). The full path of the data set is listed in the status area at the top of the page. Active data tabs are populated, inactive data tabs are grayed-out.
Figure 18: General view of the GS Run Browser window
3.3.1 The Global Action Area Buttons
Four main buttons are always available in the right hand tool bar (see Figure 18):
•
The Exit button closes the application.•
The Open button allows a user to browse the file system to find a data set to open.Clicking this button while pressing the Shift key evokes a pop up menu allowing the user to choose from a list of data sets recently opened with the GS Run Browser. Only one data set may be opened at a time, thus when opening a new data set, a message will appear asking the user to confirm closing of the current data.
•
The About button opens a dialog window providing version information about the GS Run Browser application and a button to access the GS Support Tool used to help in the troubleshooting of potential sequencing Run issues (see Section 4 for more details about the Support Tool).Software v. 2.5p1, August 2010 40
•
The Help button will provide instructions for where to find further information on the software, or will link you directly to a searchable version of the 454 Sequencing System Software Manual.3.3.2 The Tabs
The GS Run Browser application displays the various aspects of the sequencing Run results in a series of 6 tabs, as listed below.
The Overview tab contains:
•
a summary of the sequencing Run on the left•
the GS Run Processor results, if available, on the top right•
the Run Processor Manager interface, which allows the user to launch a new data processing job of the currently open sequencing Run, on the bottom right.The Wells tab displays three layers of information:
•
the raw images captured during the sequencing Run•
the regions found during image processing•
the wells found during image processing.This tab also gives the user access to well flowgrams by right-clicking on areas of the PTP Device image.
The Signals tab provides statistics on raw signal intensity and homopolymer length distributions across all the wells of the PicoTiterPlate Device for any individual flow, for either sample library or Control DNA reads.
The Reads tab provides statistics on read length and quality score results, for either sample library or Control DNA reads.
The Control DNA tab displays the accuracy metrics for the Control DNA reads (% match to their reference sequences) and other Control DNA information.
The Filters tab shows the quality filter information for the Run, including the number of wells that failed and passed each filter, for either sample library or Control DNA reads.
3.3.3 The Buttons and Plots
The images, plots and data tables displayed in the various tabs of the GS Run Browser application are scrollable and/or zoomable graphical elements. They share certain common buttons and functions, e.g. to perform the scrolling and zooming. When they do appear, these graphic elements have some or all of the following features (see in Figure 19, an example of a well flowgram window, which has most of these elements):
•
A column of buttons along the upper left edge of the graphic elements, used for navigation (including various zooming functions) and/or to save snapshot images or text files of the displayed data (see Section 3.3.4 for details). For the image area of the Wells tab, this is replaced by a unique set of controls that are overlaid near the upper left corner of the image.•
Mouse functions (pointing, clicking or dragging the mouse, touchpad, pen, etc. over the graphical element) to view data values and adjust the zoom level.Figure 19: An example Well Flowgram window showing many of the common graphical element functions
3.3.4 The Navigation and Data Capture Buttons
The buttons appearing to the left of an element have common general functions. In some cases their specific meaning is adjusted to the context of the element:
Software v. 2.5p1, August 2010 42
Button Name – Description
Zoom to default size – Some plots default to a zoom level different than ‘fit’. For those plots, this button resets the zoom level to the default initially shown.
Zoom to fit data – Fit means ‘zoom all the way out.’On plots, scale out to the limits of the data.
Zoom in – Zoom in by a factor of 1.5.On image displays, this will zoom in by this factor, centered on the middle of the display. For plots, this button zooms only the y-axis scale (use the Zoom to labels or mouse freehand zooming functions described below to zoom the x-axis).
Zoom out – Zoom out by a factor of 1.5. On image displays, this will zoom out by this factor, centered on the middle of the display. For plots, this will zoom only the y-axis scale and, unlike most zoom operations, this will zoom out past the data limits (to allow the user to get a better perspective of the data).
Zoom to x-axis labels – This button only appears in the flowgram viewers; it zooms the x-axis of the flowgram so that the nucleotide/flow characters can fit below the axis.
Save chart as image file – Save a snapshot image of the current view to disk.This will open a dialog asking for a location and file name, and then will save a PNG image file at the location specified. For Summary data tables, this saves the whole tabular area, while for all other displays the saved image contains only the visible region of the element.
Save chart data to separated values file – Save an Excel-compatible, tab-delimited text file of the spreadsheet data for this graphic. This will open a dialog asking for the location and file name to save the file. It then saves the data, along with summary information describing where the data came from, as shown below (a file portion saved from a well flowgram):

For plots, the spreadsheet file contains the data currently being plotted. For a tri-flowgram view (see Section 3.5.3), the data for all three plot subsections is saved to one file, with white space between subsection plot data. For Summary data tables, the
superset of the data.
Close – Close a flowgram window.The “x” icon in the upper right window corner will also close the window.
The image area of the Wells tab has special navigation controls described in Section 3.5.1.4.
3.3.5 The Mouse Functions
When the mouse cursor is located over the flowgram, additional functions can be performed by moving, clicking or dragging the mouse:
