| + | grainsizelist: An output file from the "timelessExtractGrainSizes.py" script. Should be a regular text document | ||
| + | -H & -V # beamsize_H and beamsize_V: Horizontal and vertical dimension of the X-ray beam in $\mu$m. Necessary to calculate the illuminated sample volume. | ||
| + | -r # rotationrange: Full rotation range used in the experiment in micrometer. Necessary to calculate the illuminated sample volume more accurately. | ||
| + | -t # samplethickness: Thickness of the sample in micrometer. Necessary to calculate the illuminated sample volume. | ||
| + | -i # indexquality: Quality of the previous indexing process in percent. Used to account for the fact that not all grains were found during the indexing. | ||
| + | -rad # radius: Boolean operator that determines if grainsizelist consists of grain volumes or grain radii. True means volumes, False means radii. | ||
| + | -hist # histogram_bins: Number of histogram bins you want to use. By default, no histogram is plotted. | ||
| + | -prop # proportion: Defines how much of the sample is your phase of interest. Can be between 0 and 1. | ||
