TSTool / Command / TSID


A time series identifier (TSID) command reads a single time series. This is one of the few TSTool commands that does not follow the Command(ParameterName=ParameterValue,...) syntax. Time series are read using one of the following commands:

  • TSID - implicitly reads time series consistent with the datastore or data type specified by the ~datastore at the end of the TSID.
  • ReadTimeSeries command, which provides general parameters to control the read, such as alias to assign.
  • ReadTimeSeriesList command, which reads multiple time series given a list of time series in a table.
  • Specific Read.... command consistent with the TSID, in order to provide controlling parameters specific to the datastore. For example, the ReadColoradoHydroBaseRest command provides parameters to control filling additional missing values with zeros.

In order to read the time series from a persistent format (database, file, or web site), the TSID must contain the datastore name (or input type), and if necessary, the input name. For example, a TSID command for the State of Colorado’s StateMod model file format is of the form:


Refer to the documentation for the datastore or input type to understand the format of the TSID. The TSTool main interface can be used to interactively format TSIDs in many cases.

After executing the command, the time series will have the identifier as originally requested, with no alias being assigned. Use ReadTimeSeries command to assign an alias to the time series, or use one of the specific read commands.

Command Editor

The following dialog is used to edit the command and illustrates the syntax of the command. Limited checks are done while editing the command (e.g., verify that a valid data interval is used). Once the command is saved, TSTool will attempt to read the time series metadata and will issue a warning if unable to read the data. Time series identifiers that include filenames should typically be adjusted to a relative path to allow the files to be moved to another location and run without errors.

The following example is for a TSID for the State of Colorado’s HydroBase database. In this case the datastore name is specified at the end of the TSID.

Command Syntax

The command syntax is as follows with the details varying based on the data source:



See the automated tests for various datastores and input types (see TSID in folder names).

A sample command file to read a time series from the State of Colorado’s StateMod is as follows. In this case the absolute paths have been adjusted to relative paths using the command editor dialog. Note also that the data source and data type are not required in this example because this information is not stored in the StateMod file.
