| - | A good start is to look for the number of assigned G-vectors. This command will do it | + | There is now a dedicated TIMEleSS tool to [[evaluation:evaluate_indexing_statistics|evaluate your indexing performance]]. |

| - | 3915 is the number of experimental G-vectors that could match our crystal structure. It decreases it time we generate a new GVE file based on a previous GrainSpotter indexing. When it increases back to 3915, it means that the loop fully started over. In the example above, we started from 3915 experimental G-Vectors, 1454 are left, we assigned approximately 60% of the experiment G-Vectors. | + | |
| - | + | ||
| - | The ratio of assigned G-Vectors is not 100% trivial to calculate as the number of matching experimental G-vectors depends on your Δ<sub>2θ</sub> and n<sub>σ</sub> parameters in the GrainSpotter input file. | + | |
