Indirect Simulation
This interface contains loaders for data created by various simulation software.
The MolDyn interface is used to import simulation data created using nMOLDYN (by
using the MolDyn algorithm), tab operates on either .dat
or .cdl files for nMOLDYN 3 or a directory containing the files extracted from
the .tar archive created by nMOLDYN 4.
- Version
- The version of nMOLDYN the imported data was exported from.
- Data
- The data file (.cdl or .dat) to load when using nMOLDYN 3 or the directory
for the export taken from nMOLDYN 4.
- Function Names
- A comma separated list of functions to load from a .cdl file.
- Crop Max Energy
- Allows the maximum energy for loaded functions in energy to be cropped, this
can be useful to remove the additional simulation data that is out of the
energy range of an instrument.
- Symmetrise Energy
- Symmetrises the functions in energy about x = 0.
- Instrument Resolution
- Allows convolution with an instrument resolution file or workspace.
- Run
- Runs the processing configured on the current tab.
- Plot Spectra
- If enabled, it will plot the selected workspace indices in the selected output workspace.
- Plot Contour
- If enabled, it will plot the selected output workspace as a contour plot.
- Save Result
- Saves the result in the default save directory.
The Sassena interface is used to load simulations from the Sassena software.
This is done through the LoadSassena algorithm.
- Sample File
- The data file (.h5 or .hd5) to load.
- Time per Data Point
- Specifies the time interval between each data point in the loaded data file.
- Sort by Q Vectors
- If checked will sort the structure factors by momentum transfer in ascending order.
- Run
- Runs the processing configured on the current tab.
- Plot Spectra
- If enabled, it will plot the selected workspace indices in the selected output workspace.
- Save Result
- Saves the result in the default save directory.
The DensityOfStates interface is used to load CASTEP simulations using the
SimulatedDensityOfStates algorithm. It supports loading
full and partial densities of states, raman and IR spectroscopy.
The following options are common to each spectrum type:
- Spectrum Type
- Selects the type of spectrum to extract from the file.
- Peak Shape
- Selects the shape of peaks to fit over the intensities extracted from the file.
- Peak Width
- Sets the FWHM to which the fitted peaks should be broadened.
- Bin Width
- Sets the histogram resolution for binning.
- Zero Threshold
- Frequencies below this threshold will be ignored.
- Scale by Factor
- Optionally apply scaling by a given factor to the output spectra.
When loading a partial density of states (from a .phonon file) the following
additional options are available (note that they will be disabled when using a
.castep file):
- Ion List
- Lists all the ions in a given file, individual ions can then be selected to be
included in a partial density of states.
- (De)Select All
- Provides a quick method of selecting or deselecting all ions in the current
file.
- Sum Ion Contributions
- If selected, the contributions of each selected ion will be summed into a
single Matrix Workspace, otherwise a Workspace Group with a
Matrix Workspace for each ion will be produced.
- Scale by cross sections
- If selected the contribution for each ion will be multiplied by the given
scattering cross section.
When loading a raman spectroscopy spectra the following additional options are available.
- Temperature
- Temperature to use in Kelvin.
- Run
- Runs the processing configured on the current tab.
- Plot Spectra
- If enabled, it will plot the selected workspace indices in the selected output workspace.
- Save Result
- Saves the result in the default save directory.
