13.4.6 Topo Layout file: filename.tpl
This file records the topographic layout information as it is entered in the topo layout editor of the
Configure Hardware dialog (see section 5.4). The information is recorded in a tabular layout identical to
the row and column structure in the Topo Layout editor. Instead of separating source and detector
numbers by a hyphen (‘-‘) a purely numerical format was chosen to make computer reading easier. Each
channel is recorded by a positive integer number (although in floating point notation) whose ‘hundreds’
represent the source position, and whose ‘ones’ represent the detector.
Therefore: Channel ‘xx-yy’ would be noted ‘xxyy’, e.g., channel 5-7 507; channel 16-14 1614.
The example below corresponds to the topo layout shown in Figure 15.

13.4.7 Probe Setup file: filename_probeInfo.mat
NIRStar14-1 automatically saves the Probe Setup file that is used for Topographic Rendering (section 18)
and the nirsLAB data analysis. This file will be saved if the user has either made use of the Topographic
Rendering capability by plotting the data online (2D, 3D or Cortex) or selected one of the available
Predefined Montages (section 5.2) having a _probeInfo.mat file.
Please refer to the nirsLAB User Manual for more information on how to create a Probe Setup file.
13.5 Hidden files: *.dat, *.avg
NIRStar14-1 presents two new files that are saved into the dataset folder as hidden, because these are
intended to be used by the acquisition software only. Both *.dat and *.avg files are required to employ
the Data Review feature (see section 15). The *.dat file is a matrix containing the hemodynamic states
displayed in NIRStar Data Visualization screen during the measurement, while *.avg is a data structure
with diverse information about measurement settings that should only be opened and used by NIRStar.
