Both DSS files and CWMS database files use pathnames. DSS provides a pathname of parts A through F separated with forward slashes, "/". CWMS database pathnames are set parameters, called Identifiers, that are separated in the pathname by dots, '.'. Depending on which type is opened, either a DSS file or a CWMS database file, the respective filters will display in the Pathname Filters located on the CWMS-Vue main window. The following sections describe the basics of each type of pathname.

Viewing DSS Pathnames

The display of DSS pathnames in the Pathname Table shows all of the pathnames by the different parts for DSS records (CWMS-Vue Main Window). You can change this display from the View menu. Available commands are Pathname List, Pathname Parts, Condensed Catalog, and No Pathnames.

The Pathname List command (Figure 1) displays the pathnames in the Pathname Table, while No Pathnames displays nothing. The Pathname Parts command (default) is the same as the Condensed Catalog, except with DSS records' D part. In the Condensed Catalog, the D part displays the date span for each DSS pathname.

Viewing CWMS Database Identifiers

The display of pathnames in the Pathname Table shows all of the pathnames by the different identifiers for the CWMS database selections (Example CWMS Database). You can change this display from the View menu. Available commands are ID List, ID Parts, and No List.

The ID List command (Figure 2) displays the data set names in the Data Set Names Table, while No List displays nothing. The ID Parts command (default) display the dataset names by parts (Example CWMS Database).

Sorting DSS Pathnames by Parts

Another way to change the display of the DSS pathnames is through sorting by pathname parts. Sorting DSS pathnames by parts is the command Search pathnames by part (default). To sort by pathname parts, from the Pathname Filters (Figure 3), decide which DSS pathname parts will be used. There is a Filter List for each individual pathname part.

An example is shown in Figure 3, where DSS filters are used to see all of the STAGE records that are observed data. From the Filter C list, select STAGE, and from the Filter F list, select OBS. The Pathname Table displays only the pathnames that fit the criteria you selected from the Filter Lists.

Another way to sort the pathnames is available from the View menu. Click Search pathnames by string. The details for this method are described in the HEC-DSSVue User's Manual.

Sorting CWMS Database Identifiers by Parts

CWMS database records can be sorted by parts, called Identifiers. Sorting the CWMS identifier pathnames by parts is the command Search pathnames by part (default). To sort by pathname parts, from the Pathname Filter decide which pathname parts to use to sort the pathname list (Figure 4). There is a Pathname Filter for each individual pathname part. The example shown in Figure 4 filters the pathnames by the following: Location - COUG, Type – Inst, Duration – 0, Parameter – Precip-Cuml, Interval – 1Hour, and Version – Decodes-Raw, which displayed one record in the Pathname Table: COUG. Precip-Cuml.Inst.1Hour.0.Decodes-Raw.

Selecting Pathnames

Once you have the appropriate list of pathnames in the Pathname Table, you can select which pathnames you want to view or manipulate. To select a pathname, double-click on a pathname in the Pathname Table, and the selected pathname will appear in the Selected Pathname List (CWMS-Vue Main Window). You can also click on a pathname in the Pathname Table, and then click Select.

To select multiple pathnames, in the Pathname Table, click on a pathname the pathname will be highlighted. Find the next pathname you would want to include in a group, hold down the SHIFT key and click. The block of pathnames will be highlighted. Click Select, and all the pathnames within that block will be added to the Selected Pathname List.

Another way to select multiple pathnames is from the Pathname Table. Click and drag across the pathnames you want, release the mouse button and the block of pathnames will be highlighted. Click Select, and all of the pathnames within that block will be added to the Selected Pathname List.

You can select individual pathnames to be in a group for selection. From the Pathname Table, select a pathname which will be highlighted. To select another not in a contiguous group, hold down the CTRL key and select the next pathname which will be highlighted. Continue to do this until you have selected all of the pathnames you want. Release the CTRL key and click Select. All the pathnames you have selected will be added to the Selected Pathname List.

You can select all of the pathnames displayed in the Pathname Table. From the Edit menu, choose Select All. All of the pathnames will now appear in the Selected Pathname List.

Clearing Selected Pathnames

To clear a pathname from the Selected Pathname List (CWMS-Vue Main Window), select a pathname and click De-Select. The pathname will be cleared from the Selected Pathname List. To clear all pathnames from the Selected Pathname List, click Clear Selections.

You can also clear groups of pathnames by using the same concepts described in selecting pathnames by using the SHIFT and CTRL keys. Once pathnames have been cleared from the Selected Pathname List, the pathnames can be restored to the Selected Pathname List by clicking Restore Selections.
