mar345 Program Manual 4 ______________________________________________________________________________________ 1. Introduction The program mar345 is a fully menu driven graphical user interface (GUI) for collecting and displaying images on a mar345 imaging plate system. The program is provided as binary executable for several computer platforms and operating systems: − Silicon Graphics: IRIX 5.x, 6.x − Digital: Compaq Tru Unix 4.x, 5.x − Linux: RedHat 5.x, 6.x, SuSE 6.x 1.1 Compu

mar345 Program Manual 5 ______________________________________________________________________________________ 2. Running mar345 2.1 Command Line The program mar345 should be started by just typing "mar345". The program, however, understands the following command line options: mar345 [−h] [−colors N] [−def XXXX] [−host HOST] [−keep] [−more N] [−noxf] [−port PORT] [−setd] The command line options are: −h Print a usage summary −colors N Use N colors for drawing images

mar345 Program Manual 6 ______________________________________________________________________________________ 2.2 Input Files The program mar345 requires the following input files to work properly: a) $MARLOGDIR/mar345.dat The program continuously saves edited parameters into this file. It is nice to find the program in the same state where you left it at startup. However, if mar345.dat cannot be found, program defaults will be used. b) $MARTABLEDIR/config.XXX XXX is a 3−digi

mar345 Program Manual 7 ______________________________________________________________________________________ The contents of the different types of log files are as follows: 1.) mar.log: All messages on the terminal output. 2.) mar.spy: Native mar345 controller messages. These messages become very important in case of hardware problems. Therefore, USE SPY should always be set. Note, that these files can become very large in size, so sufficient disk space should be available in

Do not run the program in the background and do not use this window for other purposes. The program will send important output to the window and you don’t want to miss it. At start up, the program will tell you something like: ============================================================= Prog

mar345 Program Manual 1 2 ______________________________________________________________________________________ Note: Timing is a crucial issue when operating the scanner. If the computer is very busy doing other computations, the internal clock of the program will work slower. A good check for excessive computer activity is if the X−windows server is not able to repaint the user interace at a reasonable speed. 3.4 Scanner Command Area The buttons in the command area can be used

The window comes in 4 slightly different flavours, depending on the button choice in the Collect Menu: − Single Data Set − Multiple Data Sets − Index Crystal − MAD Data The difference is, that in Multiple Data Sets one can program up to 64 data sets with the full range of parameters.

mar345 Program Manual 1 6 ______________________________________________________________________________________ In MAD Data mode "No. of images" is replaced by "No. of ϕ blocks" and a field for entering the number of images per ϕ block. It is supposed that one wants to collect a number of contiguous images at a certain position and then the same wedge of data 180 degrees away. It is not such a good idea to collect only single images at one ϕ position since the detector will have

To save parameters, press the "Save" butto

It is a good idea to always let the plate clean first before actually starting the data collection. In Multiple Data Sets mode, before actually sending the command to the scanner the mar345−Run Parameters window will pop up.
