Equalize the number of epochs across multiple datasets.
- Number of epochs. The number of epochs to include in each ouptput dataset.
- Find maximum number of epochs to equalize. Finds the maximum number of epochs that can be used to perform the equalize function, this will correspond to the number of epochs in the dataset having the smallest number of epochs. For example, if you selected three datasets with 31, 33 and 29 epochs, respectively, the maximum number of epochs will be 29.
- If number of epochs > equalized number of epochs, select random epochs in the dataset. When checked, if the number of epochs to equalize is smaller than the number of epochs in the dataset, the function will randomly select these epochs from the list of available epochs. If unchecked, the function will select the N first epochs of the dataset.

Select epochs of a dataset according to epoch data. This requires dataset(s) with epoch data fields.
- Select epochdata field. Select the epochdata field to be used as criterion to select epochs. In this example, the field is ‘RT’, corresponding to reaction times associated with each epoch of the datasets (in milliseconds).
- Logical operation and Comparison value. The logical operation to apply as criterion. In this example, epochs will be selected if and only the value stored in the field RT (i.e. the reaction time) is shorter than 650 ms.
Select epochs of a dataset according to the latencies of events.
- Select event code. Select the event code to be used as criterion to select epochs. In this example, epochs will be selected based on the latencies of the event ‘L 1’.
- If both minimum event latency and maximum event latency are unchecked, epochs will be selected if they contain the selected event (in this example, if the event ‘L_1’ occurs during the epoch), regardless of the latency of the event.
- Minimum event latency. If checked, epochs will be selected if and only if they contain the selected event and if the latency of that event is greater than the defined minimum latency. In this example, epochs will be selected if and only if they contain an event ‘L_1’ with a latency >0.2 s.
- Maximum event latency. If checked, epochs will be selected if and only if they contain the selected event and if the latency of that event is shorter than the defined maximum latency. In this example, epochs will be selected if and only if they contain an event ‘L_1’ with a latency <0.4 s.
Sort epochs of a dataset according to the values stored in an epoch data field. This requires dataset(s) with epoch data fields.
- Select epochdata field. Select the epochdata field to be used for sorting. In this example, the field is ‘RT’, corresponding to reaction times associated with each epoch of the datasets (in milliseconds).
- Sort order. Epochs can be sorted in ascending or descending order.
- Discard epochs with empty fields. If epochs do not have a value associated to the selected field (e.g. epochs with no reaction times), these epochs can be either discarded, or appended to the end of the dataset.
Sort epochs of a dataset according to the latencies of events.
