How to export data output into files
1.Select Output | Export All | ASCII, Use Wizard.
2.Select the source for output and select a profile. Click Next.
3.Choose the Break-up batch sessions into separate files option if the output for each baseline is required in its own ASCII file.
4.5.4Export Selected
This feature exports only those baselines which are highlighted in the List of Baselines window. If you select CMB File, the software writes a separate combined file for each of the selected baselines. See Chapter 3 on Page 207 for a description of the format used for this file.
Selecting ASCII, Use Wizard launches the Export Wizard utility to create output files in a pre-defined or userdefined format. See Chapter 3 on Page 111 for more information.
If multiple baselines have been selected for export, you are prompted with the Combine Multi-Base window. See
Section 4.2.8, on Page 182 .
View Export Files
This option opens the ASCII viewer to view the last output file that was written using the Export Wizard. If the Break up batch sessions into separate files option was selected in the Export Wizard, this feature will return an error since it looks for an output filename corresponding to the name of the project. In this situation, select File | View | ASCII File and then browse to the output file of interest. See Section 2.4.8, on Page 60 for more information.
4.6Tools Menu

Data features are described in Section 2.8.11, on Page 137 and Section 2.8.12, on
Page 140 , respectively.
Some features will only be accessible if a Map Window has been opened for a particular baseline.

List of Baselines
This window contains a list of all the baselines included in the project, regardless of whether or not they have been processed.
The columns listed in the shaded box are displayed in this window.
Several options are available by right-clicking on a baseline in the List of Baselines. Only those not previously discussed or referenced in this chapter are described.
Rename
Rename the baseline. The processing files corresponding to the baseline being renamed will not be over-written or deleted because this option creates a new CFG file for the baseline, which replaces the previous one.
Solution Usage
Selects which solution to load into the project.
View GPS Observations
Views all information concerning the master and remote observations being used in the baseline. See the options listed under the View/Edit GPS in Section 2.4.1, on Page 52 for information regarding the options available.
View Forward/Reverse Solution
See Section 2.4.2, on Page 52 for information regarding the options available.
View Processing History
See Section 2.4.3, on Page 54 for information regarding this feature.
View Processing Summary
See Section 2.4.4, on Page 54 for information regarding this feature.
Digital Elevation Model
See Page 47 for information regarding this feature.
View/Edit Features
Opens the Feature Editor. See Section 2.4.6, on Page 55 for information regarding this feature.
Load Features
See Section 2.4.6, on Page 55 for help loading features.
View Objects
Opens the Object Menu. See Section 2.4.7, on Page 57 .
4.8Help Menu
See Section 2.10, on Page 146 for information regarding the features available via this menu.
List of baseline columns
Baseline
The name of the baseline. An icon appears beside each baseline to indicate the status of that baseline. Icons containing question marks indicate that the baseline has not been processed. Any arrows within the icon indicate the directions that the baseline has been processed in. The same logic applies to icons containing the letters MB, which are used only to indicate that the baseline contains multiple bases.
#Epoch
The number of epochs in the remote GPB file.
#Proc
The number of epochs processed in the loaded solution.
#Feat
The number of features present in the baseline.
Solution
Indicates which solution is currently loaded.
Last Status
Indicates the status of the solution most recently processed.
