How to plot data from the Profile database using JETDSPJETDSP can plot all signals held in valid 1D and 2D Ufiles in the profile database. If the MDS+ library is available then this alternative route can be used.Getting Ufiles from the ITER Profile DatabaseTo get data from the Ufiles database click here and navigate to find the signals you require. Click on the signal and save it do disk.
Getting Started with JETDSPTo run JETDSP on a unix system, type 'jetdsp' at the Unix command line. If this doesn't work please contact your systems administrator. Reading and Plotting Ufile SignalsOn starting JETDSP, the following blank table will appear: To read a signal into the program, choose the Read Signal option from the File menu. This presents you with a dialog into which you can type the various components needed to define a signal, by default only Ufiles can be read. Click on the 'Filename' button to open a directory browser, and once a file has been selected click on the 'Signal' button to display a list of signals.Click 'Read' after you have filled in the fields. The program will warn you if the values you give do not define a signal that it can load. When the signal has been read, its name will appear in the table. The 'Read a signal' dialog is still visible, should you wish to define further signals. Click 'Done' to dismiss it. To plot all the signals, select 'Plot All Signals' from the 'Plot' menu. The signals will be plotted in a separate window. This is the View/Print window. The program can manage multiple copies of this window. Each time signals are plotted a new window is created. See here for a sample plot image. By default the whole signal name is used as the legend. This can be changed by using the 'Style editor'. By making the legend smaller the plot becomes larger.It is possible to plot only a subset of the signals. To do this mark the signals by clicking in the first column, (labelled 'M'), and then select 'Plot Marked Signals' from the 'Plot' menu. Note that a signal can be hidden by setting its plot number to 0 . To add a signal to the new window, choose 'Add Signal' from the window's 'File' menu. It will also be added to the main table, and may be used in new windows. Use MDS+ to access the data.To read data using the MDS+ routines select 'Read Signal' from the 'File' menu. The select 'MDS+' in the top row of buttons. The screen should now look like this. The server name is 'tokamak-profiledb.ukaea.org.uk' and the tree name is of the form 'tokamak'_profile e.g. jet_profile. The available tokamaks and pulses can be detemined from the webpage.To find the available signals click on the 'Browse Tree' button. |
