Program to convert SPE files to TIFF is here
Several computer programs are used to access the Princeton camera, which is connected to the Side Station Image computer. Below is the desktop with all the programs opened:
The important components will be discussed below.
Start by pressing the "Start Roper R1-6" icon, toward the upperleft of the desktop. This will load the Roper server, Exceed, Medm, the Roper.adl main window (with PVs blank), and try to open WinView/32. It may ask if you want to overwrite a file which already exists. Probably, you should say "Yes". The command window continues to process commands, then a few seconds after it ends, the Roper.adl file should have all white PV buttons filled. properly. Although WinView/32 started, the WinView window may not appear. If you want to view your images using WinView, you must start it manually at this time.
When Epics is started, the MEDM window entitled "Area Detector Control - X17B2RP1:cam1:" is displayed, as below:
If you want to use ImageJ, start it:
Load the Epics_AD_Viewer Plugin:
The window below pops up:
Display the image by pressing Start. The image may not appear, but if you adjust the image contrast, etc. with the Image menu, it should pop into view.
The important parameters to set here are,
The camera can be accessed using WinView alone, but greatest flexibility is obtained if you use the Epics interface. Starting this way enables Epics PVs to be used to control the camera, which allows automation using IDL.
The information below is out-of-date (because we don't use WinView directly any more), but there may be useful information contained herein.
After WinView is started, you need to configure the software. Some of the paramters are passed from the EPICS window. The important configuration windows are shown below:
Select 'Use Full Chip" or "Use Region of Interest" here. Accumulations should be set to 1. DO NOT set exposure time or number of images (number of frames in the movie) here, set them in in the Roper.adl window, shown above
To change the type of image file, go to Setup in the main WinView/32 window:
then select General...:
You may choose WinX Data (*.spe), TIFF (16 bit) or TIFF (8 bit). Only SPE-format files have all the experimental header data, including date and time image was collected. If you save your files as SPE, you can later convert to TIFF by using the IDL program SPE-to-TIFF (see top of this page).
This is opened with the ImageFileLabel IDL shortcut. When you press "Get Image Info", the information from the right-hand column of the ccd.adl window will be copied. If you need to change it, go back to that window, change it there, and press the Get Image Info button again. When you press "Save Image/Print Label", the image will be saved in the format set in the Data File tab of WinView. All the text information shown here will be put in the standard label, and the information added to the "AllLabels.txt" file located in the main data directory on T:
This is opened with the Notebooktext IDL shortcut. Anything you type in the box, along with a time stamp, is added to the "AllLabels.txt" file located in the main data directory on T:
