Reload Data File

will reload the current file. This is almost only useful for APS 2-ID-E files (*.mda) after changing the file read parameters (see Sec. 5.19 and Fig. 5.20).

Close File

will close the current file.

Display Scan Paramters

opens a popup window with some interesting scan parameters (see Fig. 5.9):

Figure 5.9: The scan parameters popup window

• Center and stage positions of displayed scan for X, Y and Z.

• Start energy and stop energy (will obviously be the same for images) and corresponding wavelengths.

• The scan devices, the number of pixels, pixel size and field size of the scan.

• And the scan information (Scientist, Sample and Comments). These can be edited and will be preserved if the file is saved later (File $\rightarrow$ Save As ...) or overwritten on the server (File $\rightarrow$ Save File on Server).

If you loaded a different file into SM_GUI in the meantime, you can update the popup window by clicking the "Get Current Parameters from SM_GUI" button. Actually, this happens automatically now.

Display sm_par structure

will open another popup window in which the entire sm_par structure (see Sec. 10.4) can be viewed (see Fig. 5.10). This structure holds all the information and parameters which are stored with the data file for later analysis. The following buttons are available:

Get Current Values from SM_GUI

allows to reload the structure for the currently displayed data files. Actually, by now SM_GUI should update this window automatically.

Export sm_par Structure to IDL Main Level Variable

(only available when running in a fully licensed IDL version) lets you export the sm_par structure into a variable on the IDL main level for further inspection or processing.

Print sm_par Structure to Output Log

(only available when running in a fully licensed IDL version) will dump the contents of sm_par to the output log of the current IDL session. This is done by a help, sm_par, /struct statement, which means that for array tags, the elements are not printed out.

Open New SM_GUI For File Display

will open a new instance of SM_GUI with the current file loaded initially. This might be useful if you want to look at several files at the same time.

Open File Browser

opens a separate file browser window which lets you open data files in SM_GUI (see Fig. 5.11). This is useful if you want to browse through a number of data files quickly, because you don't have to open the regular "pickfile" window each time.

Figure 5.11: The SM_GUI file browser

There are two modes of operation:

Open on selection

will open the file as soon as it is selected in the file browser (single mouseclick or keyboard selection with arrow keys). This allows you to operate the file browser with the keyboard at all, but you'll open every single file as you move through the list.

Open on double click

will open the file only if you double-click it with the mouse. This mode is useful if you want to open only particular files, but it can't be used with the keyboard (because the IDL tree widget doesn't have a keyboard equivalent to the double click).

Note that you have a similar functionality with the left and right arrows in the toolbar, which also allow you to browse through all files in a directory.

Quit

will obviously quit the program.

List of recent files

At the bottom of the file menu, you will find a list of the previously opened files, so that you can switch back to them quickly. SM_GUI will remember for each file whether it was opened locally or from the server, and reopen it accordingly. Files which were opened from the server are marked with a (*) at the end of their file name. The maximum number of entries can be set in the config file (see Sec. 5.20).
