Can only be used in combination: run nodirax, run trcell, or run indxpat.
Starts the plane-search algorithm, which groups the list of spots produced by xdisp into a list of conics. Before NODIRAX can be started, the direct beam position, the crystal to detector distance, and the detector format should be specified. NODIRAX lists intermediate results of the plane-search algorithm, together with a final list of conics, represented by the word ndlv, which stands for normalized direct lattice vector. Typically, this list should have 50 to 150 ndlvs.
Starts the cell-find algorithm. It groups the selected conics/ ndlvs into a list of planes each represented by an nrlv, normalized reciprocal lattice vector. The grouping is done by a plane-search algorithm similar to the one from NODIRAX. This is needed to construct a list of possible cells. Each cell found is used to index the selected ndlvs and, based on that, refined for a few cycles. After this, the cells are reduced, scaled to the volume specified by the volume card, and listed in order of frequency of occurrence. Before TRCELL can be started, a number of conics/ ndlvs has to be selected.
Starts the indexing of the pattern. Only the spots found by xdisp are actually indexed. A spot is considered to be indexed if a predicted spot is simulated within dmin mm of it. The program gives some statistics about the number of singles, multiples and overlaps (a predicted spot is labelled as an overlap if it is predicted within dmin mm of another predicted spot). To run indxpat the program needs the unit cell and crystal orientation, the wavelength range, the resolution, the detector format, the direct beam position and the crystal to detector distance.
