In that case, you have to set the environmental variable HKLPATH to that directory. The exact command will depend on the shell you are using to run the programs (this can be determined by typing echo $SHELL). For the tcshell and the example above, the command is:

setenv HKLPATH /home/joed/programs/hkl

HKL-2000 requires also a directory hklint for site files. Its default location is:

/usr/local/hklint

(accessing it requires system privileges), but it it can be changed to an arbitrary location, by setting the environmental variable HKLDIR. For example:

setenv HKLDIR /home/joed/programs/hklint

The anom.dat file should be placed in this directory together with subdirectories containing the site files. The site file (def.site) of each detector (home or synchrotron) should be stored in its own directory. Each such directory should be appropriately named to easily identify the specific facility and the detector.

Example:

/usr/local/hklint/Raxis4
/usr/local/hklint/SPring8-BL23-Quantum4
/usr/local/hklint/BNLX25-Quantum4

You can check how the environmental variables were set by typing the command:

env | grep HKL

License key

Additionally the license key file, cr_info, needs to be present in the /usr/local/lib directory in order for the HKL-2000 programs to run. One cr_info file may contain information about many computers and detectors. The program looks through the cr_info file for the right combination of fields that matches the given detector family and computer information. Other fields are ignored.

To obtain the license key, you need to run the access_prod program on each machine that you plan to use for running any of the HKL-2000 programs. Executing the access_prod results in the following dialog (answers in red):

• enter the name of your institution: State University
• enter the name of PI: John Doe
• enter the name of person responsible for HKL maintenance: Jane Doe
• enter names of all frame formats (detectors) you want to use: mar raxis4
• enter the number of detectors in your lab which are currently supported by HKL package: 2
• enter the name of company from which you received your license: HKL Research, Inc.
• enter HKL version number: 0.98.689
• if this is temporary license, enter the number of days you request, for permanent license enter 'noexpir': noexpir
• do you want to send automatically e-mail to hkl@hkl-xray.com in order to activate your license (y) ? n

  If the answer is y (yes), the access_prod program may automatically send an e-mail with a request for an access file: cr_info. It not always works, though. If the answer is n (no) the program will produce the following info file. You may save the info file and afterwards 'manually' send it to hkl@hkl-xray.com.

Please:

• Do not edit or alter the info file - it is processed automatically after verification.
• Do not send an info file as an attachment.
• Note that the access_prod program does not work properly if the set-up of the computer operating system is not consistent.

The example of an info file created by the access_prod program is given below (comments in italic):

HOST-NAME: p4.med.state.edu	(extracted by the program - do not edit!) NOTE: the field is limited in length to 30 characters
HOST-ID: -2035379618	(extracted by the program - do not edit!)
HOSTNAM: state.edu	(extracted by the program - do not edit!)
HW_PROV: sgi	(extracted by the program - do not edit!)
CPU-SERIAL: sgi,CPU,1762854231	(extracted by the program - do not edit!)
INSTITUTION: State University	Licensee's Institution name
PI: John Doe	Principal Investigator or Group Leader
CONTACT: Jane Doe	Contact Person
DETECTORS: mar raxis4	Detector Format Families
NO-OF-DET: 2	Number of Detectors at Home Laboratory
PROVIDER: HKL	License Provider: Rigaku Americas Corporation, HKL Research, etc
VERSION: 0.98.689	Requested Version of the Program
EXPIR: noexpir

The following are detector families to be used in the above "questionnaire":

• dip - DIP family of scanners
• raxis2 - RAXIS-II
• raxis4 - RAXIS-IV
• raxis5 - RAXIS-V
• mar - MAR imaging plate detectors (except MAR345)
• mar345 - MAR345 detector
• brandeis - Brandeis 1k CCD detector on line X12c at BNL
• unsup - ADSC Quantum-4 CCD detector
• unsup210 - ADSC Quantum-210 detector
• unsup315 - ADSC Quantum-315 detector
• un-mar - MAR CCD detector 130mm
• un-mar165 - MAR CCD detector 165mm
• un-brand - CCD Brandeis 2x2

Starting HKL-2000

After you have installed HKL-2000 and placed the access file, cr_info, in /usr/local/lib directory, the program can be started from a terminal window by typing:

HKL2000

If you receive an error message "no display name and no $DISPLAY environment variable", it means that the X windows system is not working or not configured properly. On Mac OS X, you need to start the X11 application (from the Finder's Go menu, choose Applications, then choose Utilities and select X11). You should see the X11 icon in the dock, double click on it to open an xterm window and start HKL2000 from this window.

If you receive an error message "Command not found", it means that HKLPATH is not in the executable command search path. Modify the environmental variable PATH or type a full path e.g. /usr/local/bin/HKL2000.

Note 1: Access File
To obtain the access file, cr_info, please see Access Key for details.
