# beambusters library
[](https://www.python.org/downloads/release/python-3100/)
The beambusters library (bblib) is a library that contains methods to determine the detector center directly from still diffraction patterns collected in serial crystallography experiments.
You can find more information about beambusters on [this page](https://anananacr.github.io/beambusters/).
## Installation
To install bblib, run the following command in a terminal:
```bash
pip install bblib
```
## Usage
### Configuration dictionaries
To utilize the methods `CenterOfMass`, `FriedelPairs`, `MinimizePeakFWHM` and `CircleDetection` it is required to have two configuration dictionaries, one for PeakFinder8 and another one for this library itself. The following snippet shows the general structure for both (parameters not used in your case can be omitted):
```python
config = {
"plots_flag": ...,
"search_radius": ...,
"pf8": {
"max_num_peaks": ...,
"adc_threshold": ...,
"minimum_snr": ...,
"min_pixel_count": ...,
"max_pixel_count": ...,
"local_bg_radius": ...,
"min_res": ...,
"max_res": ...
},
"peak_region":{
"min": ...,
"max": ...
},
"grid_search_radius": ...,
"canny":{
"sigma": ...,
"low_threshold": ...,
"high_threshold": ...
},
"hough_rank": ...,
"bragg_peaks_for_center_of_mass_calculation": ...,
"pixels_for_mask_of_bragg_peaks": ...,
"polarization": {
"apply_polarization_correction": ...,
"axis": ...,
"value": ...
}
}
PF8Info = {
"max_num_peaks":
"adc_threshold":
"minimum_snr": ...,
"min_pixel_count": ...,
"max_pixel_count": ...,
"local_bg_radius": ...,
"min_res": ...,
"max_res": ...,
"pf8_detector_info": ...,
"bad_pixel_map_filename": ...,
"bad_pixel_map_hdf5_path": ...,
"pixel_maps": ...,
"pixel_resolution": ...,
"_shifted_pixel_maps":...
}
```
The `pf8_detector_info` parameter is a dictionary containing the detector layout information:
```python
pf8_detector_info = {
"asic_nx": ...,
"asic_ny": ...,
"nasics_x": ...,
"nasics_y": ...
}
```
The `pixel_maps` parameter is a dictionary containing the pixel maps numpy array:
```python
pixel_maps = {
"x": ...,
"y": ...,
"z": ...,
"radius": ...,
"phi": ...
}
```
The methods `FriedelPairs`, `MinimizePeakFWHM` and `CircleDetection ` need a `plots_info` parameter if you want to save plots:
```python
plots_info = {
"filename": ...,
"folder_name": ...,
"root_path": ...,
"value_auto": ...,
"value_max": ...,
"value_min": ...,
"axis_lim_auto": ...,
"xlim_min": ...,
"xlim_max": ...,
"ylim_min": ...,
"ylim_max": ...,
"color_map": ...,
"marker_size": ...
}
```
### Calling the methods
To calculate the refined detector center of raw data frame as a numpy array using the following methods:
```python
from bblib.methods import CenterOfMass
center_of_mass_method = CenterOfMass(config=config, PF8Config=PF8Config, plots_info=plots_info)
center_coordinates_from_center_of_mass = center_of_mass_method(
data = ...
)
from bblib.methods import CircleDetection
circle_detection_method = CircleDetection(config=config, PF8Config=PF8Config, plots_info=plots_info)
center_coordinates_from_circle_detection = circle_detection_method(
data = ...
)
```
The `FriedelPairs` and `MinimizePeakFWHMmethod` need an initial guess for the refined detector center coordinates ` initial_guess = [x_0, y_0]`
```python
from bblib.methods import MinimizePeakFWHM
minimize_peak_fwhm_method = MinimizePeakFWHM(
config=config, PF8Config=PF8Config, plots_info=plots_info
)
center_coordinates_from_minimize_peak_fwhm = minimize_peak_fwhm_method(
data = ..., initial_guess = ...
)
from bblib.methods import FriedelPairs
friedel_pairs_method = FriedelPairs(
config=config, PF8Config=PF8Config, plots_info=plots_info
)
center_coordinates_from_friedel_pairs = friedel_pairs_method(
data = ..., initial_guess= ...
)
```
