The following is a brief outline of data collection operations using the SMART system. In this help sheet your entries are given in boldface type. All entries should be terminated with <Enter> unless otherwise noted. If there is a user-defined name it will be set out in bold-face italics. Thus the instruction to type mkdir mydir means that you should choose some directory name, for instance "goodies", and then enter mkdir goodies. There are no commands which use the curly bracket as part of their syntax.
WARNING! This program runs from a DOS prompt. File names and directory names are limited to eight characters, no spaces. DOS really doesn't like spaces in filenames or directory names. DOS is also case-insensitive. You can mix uppercase and lowercase letters and DOS won't care. However, working with the files will be easier later on if you do NOT use explicit upper-case letters in file names.
MAKE WORKORDER: Fill out your workorder before you start work.
USE LOGBOOK: Sign on in the logbook with the date and time, your name, your P.I.'s name and the directory name for your sample. These requirements are requested by the Office of Radiation Safety, please take the time to comply with their request. Record the temperature on the low-temp apparatus and the kV and mA settings currently displayed or which you plan to use. Also use the logbook to record any apparent anomalies or malfunctions.
START UP SMART
The computer screen should show a blank blue screen. The
prompt should display C:\FRAMES>.
For purposes of discussion we
will use C:\FRAMES to mean the "base directory".
If it shows the black windows background, start a DOS Prompt session by double-clicking on the Command Prompt icon in the upper right corner of the screen. This will drop you to the bluescreen with the C:\FRAMES> prompt. You now want to create a sub-directory for your data, transfer to it and start the SMART program.
YOU MUST CREATE YOUR SUBDIRECTORY AND USE IT! Failure to do so trashes the machine for everyone else. The procedure is as follows.
C:\FRAMES>mkdir dirname
C:\FRAMES>cd dirname
C:\FRAMES\DIRNAME>smart
If the blue command prompt screen remains after you have typed smart and pressed <Enter>, pressing <ALT/TAB> will switch you to
the SMART program that will now be running.
COLLECT YOUR DATA
The SMART program will now start up. You will use the SMART program to turn up the power on the X-ray generator and to control the diffractometer. You will mount your crystal, center it, determine the cell dimensions and crystal quality, and collect your data frames (if the crystal is of sufficient quality to justify it). Procedures for this are covered in the Detailed Outline Procedures for Data Collection Help File
At the end of data collection, return the goniometer to the home position with the block towards the user and reduce the power levels on the X-ray generator to the standard settings (50 kV and 30 mA). Then exit the SMART program (<alt/f>, X, <cr>, <cr>) and transfer your data to the Linux PC ("ChexCSD").
TRANSFER YOUR DATA
The data is transfered with an FTP program which is set up to automatically connect to chexcsd. The automatic procedure is invoked as follows:
C:\FRAMES\DIRNAME>goftp
The computer will ask you to log on. The user name is smartuse (note, no "r") if you run on the older SMART system and apexuser on the newer APEX machine. The password can be obtained from Dr. Hollander or Dr. Oliver. Now you will create a subdirectory for your data on the Linux PC disk. Which account you login to is important due to the differences between the machines. Make sure you login to the correct account for the machine that you collected data on.
YOU MUST CREATE YOUR SUBDIRECTORY AND USE IT! Failure to do so trashes the machine for everyone else. The procedure is as follows. Ignore the various messages put out by the FTP program.
ftp>mkdir mydir (Note: "mydir" and "dirname" do not have to be the same, but they can be if you want. Many people find that it helps keep things straight if they are.)
ftp>cd mydir
ftp>ls (The output should show no files at all. If it shows files, that means you are in someone else's subdirectory, or still in the main directory. If this happens, don't transfer your data! Type exit and restart the operation with a different directory name.)
ftp>bin
ftp>mput *.* (Output will show your files being transferred. This will take a few minutes under normal cirsumstances. The machine will report the data transfer rate. If the rate is much less than 500, and there is no great activity on bluechex, plese let Dr. Hollander know.)
ftp>exit (Exits the FTP program and returns to the DOS command prompt.)
CLEAN UP AND SIGN OUT
C:\FRAMES\DIRNAME>framedel Now that we have transferred the data to chexcsd, we need to clean up the disk on the Pentium. If there have been no errors during your data transfer, this is a safe operation, since there is a complete copy of your data on chexcsd.
C:\FRAMES\DIRNAME>cd ..
C:\FRAMES>
You should now sign out in the Log Book, fill in the relevant information on your Workorder and take your Workorder and put it in the appropriate location (currently the "Need Data Entry" tray on Dr. Hollander's desk in room 32).
You will now integrate your data using the usual procedures as
covered in the Default
Procedures for Data Integration Help File.
