The Manage Tplot and GUI Variables option allows the user to (1) import TPLOT variables into GUI Variables, (2) export GUI Variables into TPLOT Variables, (3) delete GUI variables, and (4) view/edit the meta-data associated with various GUI variables. The Load Single File option allows the user to load data from CDF or ASCII files in his local computer. After this, the CDAWeb Data Chooser window closes and we can work with the data we have downloaded. This last window is the same as when we import data from an arbitrary CDF file. After the download is complete, we get a message that informs us that the download was successful (or not) and another window which allows us to specify the name of the tplot parameter names. Clicking on the “Get CDAWeb Data” button downloads the requested data set. We can also define an optional prefix for the resulting variables, for example “artemis_”. If we want to keep the downloaded CDF files, then we should check the checkbox “Save local CDF file”. It is also important to select a “Local CDF directory” which is writable, because that directory will be used to download files for the CDAWeb data repository, even if we do not retain those files. We have to pick dates that are within the availability dates of the particular data set we have selected. We can select the start and end dates and times using the calendar widget.
Expand the data sets and select one or more data variables (using Ctrl+Click to select multiple variables). This gives a list of all available data sets and the dates of availability of each data set. To use the tool, first select the mission name (for example, “ARTEMIS”) and the type of the instruments (for example, “Magnetic Fields (space)”) and then click the button “Find Datasets”. It opens a new window where the user can select a HAPI server, view the datasets in that HAPI server, and load a particular dataset for a particular time span. The "Load Data using HAPI" dialog allows the user to load data using a HAPI web service.
When you have loaded all the data you want, click the Done button below the data tree. Messages regarding the load process, data, and/or status of the window will be displayed here. The user can also use the Clear All button below the data tree to delete all data.Īt the bottom of the window is a status bar. The data tree will be updated to reflect the deletion. The left hand side of the window contains the data selection area and the right hand side of the window displays data that has already been loaded.ĭata can be removed at any time by making a selection in the data tree and clicking the trash can. In general, we have to choose the instrument, a data range and then we have to click the arrow to load the data into SPEDAS. Each mission has its own way of loading data with GUI elements specific to the mission.
