# Train element parameters
> Train element parameters in ABBYY FlexiLayout Studio: prepare a training set, and then apply values from the Choose Trained Element Parameters dialog box.
Element training is used to automate the configuration of individual parameters for elements of simple types. You can train a new element or correct the parameters of a previously created element if necessary.
## Prerequisites for element training
* For the element to be trained, a correct **Reference layout** or **Matched layout** on several pages is required.
* All pages to be included in the training set must be marked as **Use for Training** on the **Batch** tab.
You can either create a new element and draw its region on the image using the **Create New (Ctrl+Space)** 
tool or draw a location for an existing element of the tree using the **Draw Location** 
tool.
## Train an element
On the element's shortcut menu, select **Train Element** → **Train Element Parameters**. The **Choose Trained Element Parameters** dialog box opens, showing the parameters of the trained element and their values. Names of dependent parameters are indented.
From the **Show** drop-down list, select **modified parameters only** to see only those parameters which were modified during training, or select **all parameters** to see all parameters of the element.
Select the checkbox to the left of the parameter name to use the training result for this parameter. You can select the checkbox next to the **Parameter name** caption to select all modified parameters.
The new values of the selected parameters are saved.
