Saving the Classifier, Labels, and Project Parameters

As described in Creating a New Project, all data associated with a given behavior classifier is stored in a JAABA project file with the extension .jab, including the project parameters, classifier, and training data labels and locations. These can be saved to the current .jab file by selecting File->Save or to a new .jab file by selecting File->Save As....

Creating Different Versions of a Behavior Classifier

We often find it useful to create different versions of a behavior classifier. This can be thought of as creating a "restore point" that we can go back to if we do not like the modifications to the classifier we make. For example, we might do this if we have a classifier that is working fairly well, but we want to see what happens if we add a new type of data. To do this, we use the File->Save As... to create a new .jab file. Then, we can go back to the previous .jab file if we are unhappy with the changes we make.

Classifier's Predictions

Saving Predictions

After training a classifier, the whole trajectory of a animal, the whole experiment, or all the experiments can be classified by selecting one of the options under the Classifier -> Classify menu, see Examining the Classifier's Predictions for details. The classifier's predictions and raw output scores can be saved to a file for several of the options under this menu. The saved predictions can also be used as input for other projects.

Current animal: Predicts the behavior for all frames for the current animal and allows the user to view these results within the current JAABA session, but does not save the predictions to a file.
Classifier -> Classify -> Current Experiment -> Don't Save: Classifies all animals for the current experiment/video, and allows the user to view these results within the current JAABA session, but does not save the predictions to file.
Classifier -> Classify -> Current Experiment -> Save to default: Classifies all animals for the current experiment/video and saves to the scores file within the corresponding experiment directory. The name of the scores file within the experiment directory is the same for all experiments, and is specified during the project setup as Score/Output File Name.
Classifier -> Classify -> Current Experiment -> Save to different: Classifies all animals for the current experiment/video, then prompts the user for the location to save the scores to, and saves to this file.

Classifier -> Classify -> All Experiments -> Don't Save

not

Classifier -> Classify -> All Experiments -> Save to default: Classifies all animals for all experiments/videos, then saves to the scores file within each corresponding experiment directory. The name of the scores file within the experiment directory is the same for all experiments, and is specified during the project setup by Score/Output File Name.
Classifier -> Classify -> All Experiments -> Save to different: Classifies all animals for all experiments/videos, then prompts the user for a filename that will be used for all experiments. The classifier's predictions for each experment are stored into this selected filename within its corresponding experiment directory.

Loading Predictions

Previously saved predictions can be loaded from file into the current JAABA session. These loaded scores will be shown in the bottom portion of the Automatic Timeline if Loaded is selected from the pop-up menu on the left. Predictions can be loaded by selecting any of the options under the menu File -> Load Scores:

File -> Load Scores -> For current experiment from default location: Loads the scores for the current experiment from the default scores file within its corresponding experiment directory. The name of the scores file within the experiment directory is the same for all experiments, and is specified during project setup as Score/Output File Name.
File -> Load Scores -> For current experiment from different location: Prompts the user for a file location, and loads the scores for the current experiment from that file.
File -> Load Scores -> For all experiments from default location: Loads the scores for all experiments from the default scores file within each corresponding experiment directory. The name of the scores file within the experiment directory is the same for all experiments, and is specified during project setup as Score/Output File Name.
