The Real Time Data Quality step is a real time display that allows plotting the information generated by the Spectral Comparison processing step (under Quality Analysis category). It generates a real time map using as horizontal axis the header value defined under the Trace header containing horizontal coordinate and as vertical axis the header value located under the Trace header containing vertical coordinate.

Trace header Select trace header to be used as horizontal axis for the real time map.
Vertical range: In the current version of this real time display, it is mandatory to define the vertical range of the map either by using user-defined minimum and maximum values or by using an auxiliary SPS geometry file. The maximum value for the vertical coordinate will be automatically updated if the current horizontal trace header value is larger than what is pre-defined.
Manually set vertical range If checked, the minimum and maximum horizontal ranges are used-defined and set as specified under Vertical axis min. and Vertical axis max..
Set range from SPS file(s) If checked, the minimum and maximum horizontal ranges are specified by an auxiliary SPS geometry file selected under browse button.
Vertical axis min. Enter minimum value of the vertical coordinate to be displayed.
Vertical axis max. Enter maximum value of the vertical coordinate to be displayed.
Attribute color scale The map of the real time display is displayed with the color scale bar as defined using the select buttn. By default the information is plotted with the default color bar (rainbow).
Trace header containing attribute for display: Select the trace header with the information to be colored in the real time map. With the Spectral Comparison step, we can select either the spectral semblance value of the dead/live flag.
Trace header Select the trace header to be used to color the real time map.
Display tab: This real time display allows plotting simultaneously more than one map within the same tab view. This is a useful option to plot, for example, the value of the spectral semblance along with the dead/live flag.
Add display to a tab If checked, the map is added to a display tab already open.
Unique tab name Enter unique tab name where the map is going to be displayed.
Map scale: The real time map can be plotted using different types of scale.
Scale to fit view If selected, the map is automatically scaled to fit the current view.
Scale to fit dimensions If selected, the map is automatically scaled to fit the dimensions defined by the user.
Height (in pixels) Enter the height of the map in number of pixels.
Width (in pixels) Enter the width of the map in number of pixels.
Scale to fit horizontal If selected, the map is automatically scaled to fit the current view horizontally.
Scale to fit vertical If selected, the map is automatically scaled to fit the current view horizontally.
Map title Enter map title to be displayed in the display tab.
Attribute label Enter attribute label.
Output map file name Enter, or browse, the name of the file where the map is going to be saved. The map final map will be stored in a .baf format.
Usage:
Time Slices is a process used for either display of selected time slices as a display option, or as a tool to convert the data into a form suitable for specific processing.
Input Links:
1) Seismic data in sorted by CMP Line (record key) and CMP Location (mandatory).
Output Links:
1) Seismic data sorted by Slice Number and CMP Line (mandatory).

Parameter Description:
All input data If checked, time slices will be made from all of the data. This is likely to be the most suitable option for further processing of the data.
Selected time slices If checked, those time slices specified by the following parameter values will be output. This is likely to be the best data display option.
Time of first slice (ms) The first slice output will be drawn from the data samples at the specified time.
Time of last slice (ms) The last slice output will be drawn from the data samples at the specified time.
Time slice increment (ms) Time slices will be output with the specified time increment (to the nearest sample)..
Create RMS amplitude slices If checked, each output time slice sample value will be the root mean square value of all the specified samples above and below the that sample.
Samples above slice The number of samples above each output slice sample that will be used to calculate the RMS amplitude.
Samples below slice The number of samples below each output slice sample that will be used to calculate the RMS amplitude.
Usage:
Time Slices to Traces is a process used to convert time slices required for some specific processes such as PSPI Migration and Footprint Filter back into the standard time trace domain data.
Input Links:
1) Seismic data in sorted by CMP Line (record key) and Slice Number (mandatory).
2) Original seismic data CMP Line (record key) and CMP Location (3D) or CMP (2D) (optional).
Output Links:
1) Seismic data (mandatory).
