About DL Convert
DLConverter is a Windows based data conversion program made to convert "mass amounts"
of diffraction data; the end product of modern fast detectors that can scans
in seconds/minutes - rather than hours/day. As many peak fitting programs do not
like zero counts, DL-convert has the option of adding one count to each channel.
What's new in version 1.3
New features of DL Convert (version 1.3)
- Converts from Energy (kev) to Two-Theta (degree) with linear interpolation.
- Converts SRS Angular Dispersive Data (beam lines 2.3 and 9.1) to Xfit, Cpi, Gsas and Xy output formats.
- User definable columns format,
- Normalisation to the monitor,
- Converts and plots the monitor data.
- Converts all data from SRS 16.4 ASCII all three detectors simultaneously.
- Auto-detects the timer and the detector files,
- Set the file and directory name with files informations.
- Allows quickly a graphical view of the results.
- Converts ORTEC MCA Binary chn Data to Xfit and Cpi formats.
Features of previous DL Convert
The DL Converter program is able to sum different datasets from different SRS 16.4 ASCII files to a single file.
This option has been required by several users who wanted to get a better precision of analysis of the Xfit file
which has been converted after summing.
The program allows a one or two steps conversion. The user can select all the SRS MCA files he wants to sum,
choose the Xfit options and then convert the data. The two steps conversion will only summed the SRS MCA files in a
single file and the user can do as many conversions as he wants.
There are two kind of rebinning. The first one will rebin the data from two datapoints to one and the second one will rebin
the data from four datapoints to one. The rebinning applies for nearly every conversions. The only exception is the MCA files.
- Allows the averaging or the rebinning of data
- Allows to convert a new input file (*.xy) to Xfit, CPI and new GSAS output files
- summing of SRS 16.4 ASCII datasets in a single file
- Conversions from Energy (keV) to D-Spacing (Angstrom) or Two-Theta (Degree), X,Y data non-interpolated
- Allows the Constant Step conversion Q = x / d
- Saves and Loads parameters in an *.ini file
- Checks that SRS files are in a good format
- Allows user to control the main menu via keyboard
The second important modification is that it is now possible to convert the SRS and the Argonne file to D-Spacing(Angstrom)
or Two-Theta (Degree). Those conversions are made with X and Y non-interpolated.
The conversion is done thanks to the following equations :
- d-space = Lambda / (2 * sin(2_theta / 2)) : Bragg equation
- E(keV) = 6.199 / (d_space * sin(theta_angle of Energy Dispersive detector)) : Energy equation
E is the photon energy
d-space is the lattice-plane spacing
2_theta/2 is the Bragg angle
Lambda is the wavelength
The output files consist of two columns of data. The first column represents the Dspacing or the Two-Theta values and the
second column represents the counts. The A value given by the user is the Starting keV and the B value given by the user is the Step keV.
This new version allows the user to choose the column format between "Same as Input", "Single Column" and now
"10 Columns Output". This was added because it was convenient for some applications.
The DL Convert (version1.21a) allows the conversion of the Constant Step Q = x / d. The user can define the value of x
he wants as different users prefer to use x =1, x = 2 or x = 2*PI. This conversion is allowed from the SRS or
the Argonne files to D-Spacing(Angstrom). It is now possible to convert SRS single and multiple spectrum files.
The next new feature is the possibility to save parameters in an *.ini file. All the current parameters will be saved in
one file. It will be possible to load this file at any time and a default parameters option will replace the default
- SRS 16.4 ASCII - Xfit, CPI, Gsas and Xy
- SRS Angular Dispersive Data - Xfit, CPI, Gsas and Xy
- ARGONNE Energy Dispersive Data - Xfit or CPI
- ORTEC MCA Binary chn Data - SRS 16.4 ASCII
- XY Column Files - Xfit, CPI and Gsas
Conversion Formats Supported
- Normal (*.dat extension)
- Energy (keV) to D-Spacing (Angstrom) (*.xy, *.prn or *.txt extension)
- Energy (keV) to Two-Theta (degree) (*.xy, *.prn or *.txt extension)
DL-Convert presently works converting Energy Dispersive Powder Diffraction
data in the following formats:
- SRS Daresbury beam-line 16.4 energy dispersive data (single or mutiple spectra in a single file)
- Example DL 16.4 raw Data file (normally a *.dat extension)
- Example output file in XFIT compatable format (normally a *.dat extension)
- SRS Daresbury beam-line 9.1 and 2.3 angular dispersive data (single or mutiple spectra in a single file)
- Example SRS angular dispersive data file (coming soon)
- Argonne energy dispersive data
- Example Argonne data file. Data collected at intervals (e.g. one data per minute) so the file extension reflects the particular increment of data collection
- Argonne File For example, run15.001, run15.002, run15.003, etc...
- ORTEC MCA binary data file
- Example MCA data file (coming soon)
- XY Columns data file
