Introduction

Markers are items marking events or time selections in traces.
They have a position in time in seconds, a duration (which can be zero), a label, a numerical value.
Two more information can be optionally added : the colour and the targeted channels.

A marker with no targeted channels is called Global.

That means they mark a position or a time selection or an single event global to all traces.

Marker manager

AnyWave allows managing markers using a UI.
When loading a data file, if markers are detected within the file they will be inserted in the list of current markers and appear in the following window:

Editing markers

Right click on a colum in the marker list to edit its value if possible.
You can change the position, the duration, the value and the color.

Save, delete, rename

Use the right click button of the mouse to make the contextual menu appear.
Many options will allow you to handle markers quickly.

MRK file format

It is a text file with tab separated values (tsv file).
Lines starting with // will be ignored.

There are 4 mandatory columns:

#1 label

#2 numerical value associated (-1 for no value)

#3 position in seconds in the file

#4 duration in seconds (0 for single markers)

Columns 5 and or 6 can be added to store respectively the colour and the targeted channels.

Colours values must be store using the following format: #RRGGBB
Values for Red Green and Blue must be in hexadecimal.
Example for red color : #FF0000

Targeted Channels must be a coma separated list of electrodes labels: A1,A2,Fp2
