= Fields of the Event Structure =<br />
<br />
Every incoming marker instatiates a new [[BrainStreamImportantConcepts#SecEvents|event]. The event structure contains a number of fixed fields:<br />
<pre>event.name : name of the marker<br />
event.time : time [s] referred to number of acquired samples<br />
event.brainstreamversion : current version of [[BrainStream|Brain Stream]] <br />
</pre> If a DATA timepoint is specified for the event, the event structure also contains the following fields: <br /><pre><br />
event.BRAINSTREAM : contains information required for internal [[BrainStream|Brain Stream]] processing<br />
.data.raw : raw data [channels x data]<br />
.trial.time : start of data segment [s]<br />
.samp : always set to 1<br />
.offset : start of data [#samples] <br />
.duration : number of samples<br />
.hdr.Fs : sample frequency <br />
.channels.* : see remarks below <br />
.labels.* : see remarks below<br />
.Cal : raw data calibration matrix<br />
.nChans : number of channels<br />
.label : all channel labels (compatible with fieldtrip)<br />
.orig : always original header information<br />
.usedcap : name of cap used in current block (user should take care of further handling) <br />
.trial : same as event.data.trial <br />
</pre><br />
<br />
*: channel and label information can be grouped together based on settings specified for corresponding hardware device topic in the blocksettings. It uses fieldrips <tt>ft_channelselection</tt> function to match channels that belong to certain groups, like 'EEG' or 'EOG'. The data for the selected channels appears in a separate field. For example, if you defined a group of eeg electrodes, the data for these electrodes shows up in event.data.eeg. See [[Http://fieldtrip.fcdonders.nl/reference/ft_channelselectionChannelSelection|http://fieldtrip.fcdonders.nl/reference/ft_channelselection channel selection]] on the FieldTrip website for more options.<br />
<br />
Depending on the utilized data source, additional fields might be present inside the hdr structure.<br />
<br />
In addition, requested copies of global variables appear as separate fields of the event structure (for more information see the [[BrainStreamImportantConcepts#SecVariables|Global Variables] section).<br />
