 After you loaded a file you should modify the parameters. For this, click on ''Transformation'' and ''Edit parameters''. You will see a window like the one to the right. Enter all necessary parameters. Necessary are usually these ones:
-  * Cell parameters: cell_a, cell_b, cell_c in Angstrom; cell_alpha, cell_beta, cell_gamma in degrees (typically taken from [[software:maud|Maud]] refinement)
+  * **Cell parameters**: cell_a, cell_b, cell_c in Angstrom; cell_alpha, cell_beta, cell_gamma in degrees (typically taken from [[software:maud|Maud]] refinement)
-  * Lattice type: P = primitive, F = face-centered, A = A-centered, ...
+  * **Lattice type**: P = primitive, F = face-centered, A = A-centered, ...
-  * Distance = sample-detector distance in µm (typically taken from [[software:maud|Maud]] refinement)
+  * **Distance** = sample-detector distance in µm (typically taken from [[software:maud|Maud]] refinement)
-  * O-matrix (check the [[dac_experiments:geometry|concept of the O-matrix]] if you are not sure)
+  * **O-matrix** (check the [[dac_experiments:geometry|concept of the O-matrix]] if you are not sure)
-  * Omegasign = rotation direction (1 = clockwise, -1 = counterclockwise)
+  * **Omegasign** = rotation direction (1 = clockwise, -1 = counterclockwise)
-  * Tilt: Be careful with this one: Tilt in ImageD11 is sometimes not the same as tilt in other software! (usually keep 0 and refine later)
+  * **Tilt**: Be careful with this one: Tilt in ImageD11 is sometimes not the same as tilt in other software! (usually keep 0 and refine later)
-  * Wavelength in Angstrom
+  * **Wavelength** in Angstrom
-  * y_size, z_size: size of one pixel in y direction and z direction in µm
+  * **y_size**, **z_size**: size of one pixel in y direction and z direction in µm
-  * y_center, z_center: pixel coordinates of the beam center (usually taken from [[software:dioptas|Dioptas calibration]]: ''y_center = Dioptas Center X'' and ''z_center = 2048 - Dioptas Center Y'')
+  * **y_center**, **z_center**: pixel coordinates of the beam center (usually taken from [[software:dioptas|Dioptas calibration]]: ''y_center = Dioptas Center X'' and ''z_center = 2048 - Dioptas Center Y'')
+  * Supplementary parameter **cell_sg**. You can also provide your material space group. This has to be done manually with a text editor and can not be done using the Graphical User Interface. If the space group is provided, ImageD11 will use xfab for generate unique hkls.
