Create a fit model
In order to propagate your fit from one image to the others, you will have to create a
Fit Model. To do so, select the menu item
Image fit > Create a fit model.
In the dialog that comes up,
- choose your peak profile,
- add fit of sub-patterns that you want to propagate (the
.dat files you got in Manual fit of active dataset),
Save the model with a
Propagate the model
Select the menu item
Image fit > Fit multiple images: automatic. You'll have a dialog to
- select the images to work on, first image should be the one you have a model for,
- open a starting fit model or results from a previous fit (file with a
- choose a level of plot
- No plot: nothing
- Mapplot: shows the results of the fit once per image, in 2-D,
- 1-D minimal: shows results of fits as diffractograms for each azimuth angle and each image selected. This can take a while, be careful!
- 1-D intermediate: more,
- 1-D verbose, even more, you should not really use those options, unless you want to understand what is going on.
- Save fit automatically, yes or no,
- Stop calculation or proceed to next dataset in case of problems,
- Fit region width factor: this parameter is used to restrict the region over which a peak is fitted. If the fitted peak becomes too large and goes over other peaks, reduce this parameter.
I you choose to save the fit results automatically, fits will be save in files called
corresponding to each image you worked on.
Otherwise, you will be asked to give a name. To avoid problems later one, use the same naming conventions.
Those files are in text format. Have a look at them if you want to dig out some of the fit results. It should be straightforward.
