- | The time required to perform an image selection model optimization search depends on the number of models being generated/examined. The number of models examined during the search is determined by the selected image selection model categories to search (image filtering, combined z score, group bin) as well as settings specified in "Settings" -> "Image Selection Optimization Settings". If the search space is large, it may take hours to finish the optimization. | + | The time required to perform a search depends on the number of models being generated/examined.

Search runtime is proportional to the number of evaluating samples. Evaluation methods also influence the search execution time. The 'p-value of Poisson' and 'curve fit residual' methods take approximately the same amount of time. The 'Leave-one-out' method takes longer, and is proportional to the number of evaluating samples. For example, to finish a search using 10 evaluating samples, 'leave-one-out' will take approximately 10-times longer than either 'curve fit residual' or 'p-value of Poisson'. | Search runtime is proportional to the number of evaluating samples.

After evaluating samples and parameters have been selected, click the button "Click to check" adjacent to the label "Time to finish: ". A quick test will be performed (approximately 10 seconds), after which the estimated time necessary to perform the full search is displayed. | After evaluating samples and parameters have been selected, click the button "Click to check" adjacent to the label "Time to finish: ".
