 The optode template contains the layouts of the transmitting and receiving optodes. This file contains different groups of layouts, also called optode templates or montages. Each indiviudal layout has an unique ID, which is stored with the measurement. It can be read in using **[[:​reference:​ft_prepare_layout]]** and used for plotting. See also the [[/​tutorial/​layout]] and [[/​tutorial/​plotting]] tutorial. The optode template contains the layouts of the transmitting and receiving optodes.

-The project file can contains ​data that was added after the measurement,​ e.g. events extracted from the trigger channel, or events that were manually added after the measurement. This makes the project file relevant in **[[:​reference:​ft_definetrial]]** and Artinis provides a custom trial function to parse this file and use it for segmenting the continuous data in trials. ​ Furthermore the project file can contain spatial 3D MNI-coordinates of the optodes. Note that the project file can refer to multiple recordings, but also that one oxy3/oxy4 file can be included in multiple project files. This means that there is no guaranteed unique mapping between oxy3/oxy4 files and project files.+The project file can contain ​data that was added after the measurement,​ e.g. events extracted from the trigger channel, or events that were manually added after the measurement.
