Firstly, you can choose If you use \fB--peaks=zaef\fR, indexamajig will use a simple gradient search after Zaefferer (2000). You can control the overall threshold and minimum squared gradient for finding a peak using \fB--threshold\fR and \fB--min-gradient\fR. The threshold has arbitrary units matching the pixel values in the data, and the minimum gradient has the equivalent squared units. Peaks will be rejected if the 'foot point' is further away from the 'summit' of the peak by more than the inner integration radius (see below). They will also be rejected if the peak is closer than twice the inner integration radius from another peak. -If you instead use \fB--peaks=peakfinder8\fR, indexamajig will user the "peakfinder8" peak finding algorithm describerd in Barty et al. (2014). Pixels above a radius-dependent intensity threshold are considered as candidate peaks. Peaks are then only accepted if their signal to noise level over the local background is sufficiently high. Peaks can include multiple pixels and the user can reject a peak if it includes too many or too few. The distance of a peak from the center of the detector can also be used as a filtering criterion. +If you instead use \fB--peaks=peakfinder8\fR, indexamajig will user the "peakfinder8" peak finding algorithm describerd in Barty et al. (2014). Pixels above a radius-dependent intensity threshold are considered as candidate peaks (although the user sets an absolute minimum threshold for candidate peaks). Peaks are then only accepted if their signal to noise level over the local background is sufficiently high. Peaks can include multiple pixels and the user can reject a peak if it includes too many or too few. The distance of a peak from the center of the detector can also be used as a filtering criterion. Please notice that the peakfinder8 will not report more than 2048 peaks for each panel: any additional peak is ignored. You can suppress peak detection altogether for a panel in the geometry file by specifying the "no_index" value for the panel as non-zero. |
