# Epoching Data
|
|
|
Epoching data is useful as it allows you to explore the data in more ways. It is important to use the following way to epoch the data reather then the native EEGLAB method. This method does the exact same thing as the EEGLAB epoching except it understands the marks structure and will keep it intact.
|
|
|
|
|
|
To get started go to:
|
|
|
* *Tools-> Marks -> epoching/concatenate data -> Epoch Data into Regular Intervals*
|
|
|

|
|
|
The pop up will ask you for:
|
|
|
* Epoch reoccurance interval: how seperated the epoces will be.
|
|
|
* Epoch Time limits: the lentgh of time that surrounds the epoch.
|
|
|
* Whether or not you want to remove the baseline????????????????????????????????
|
|
|
* And finally the name of the new epoched set.

# Concatenating Data
|
|
|
To get recombined the epoched data back into continuous form go to:
|
|
|
* *Tools-> Marks -> epoching/concatenate data -> Concatenate Epoches into Continuous Data*
