Colours of channel waveforms and labels may be modified by changing the corresponding entry in the Montage Editor configuration file BesaME.cfg, which is separately stored for each user.

The configuration file is located in the current user's folder, usually C:\Users\<User name>\Documents\BESA\<Research_X_Y>\Settings. Here, <Research_X_Y> specifies the BESA Research version (I.e. Research_7_1_ and <User name> is the user name which was used to log on to Windows.

The colours may be set in the section [Colors]. If this section is not available, please add the [Colors] line (no quotes) at the end of the file and write the color modifications below this line.

Various features for various group of channels and channel subselection can be set. the convention is: FeatureChannels_Sub

Following features can be used:

• ColText
• ColPlot
• ColWave

The "ColText..." colours specify the colours of the channel labels. The "ColPlot..." colours specify the colours used for display in the Montage Editor. The "ColWave..." colours specify the colours of the channel waveforms. It is recommended to use the same or similar colour for the 3 corresponding entries.

Following channel groups can be used:

• RecordedElectrode
• VirtualElectrode
• InterpolatedElectrode
• SingleDipole
• RegionalSource
• SpatialComponent
• Magnetometer
• Gradiometer
• InterpolatedChanMEG
• IntracranialChannel
• PolygraficChannel
• BadChannel
• UnavailableElectrode
• RecordedMontageChannel*
• VirtualMontageChannel*
• MEGMontageChannel*
• UnavailableMontageChannel*
• AddChanMontage

The "...RecordedElectrode..." indicate which type of channel should be affected.

*Note that there are special groups "...MontageChannel". For this group only ColPlor feature can be used.

For channel groups: RecordedElectrode, VirtualElectrode, InterpolatedElectrode, SingleDipole, RegionalSource following sub selection should be added for "ColWave..." feature:

• Left
• Right
• Mid

The "..._Left" sub selection indicates that only sensors located over left hemisphere will be affected by this setting.

Note that this subselection can be used an is obligatory for EEG sensors and sources.

For ColPlot feature following sub-selection can be added for sensors:

• Selected
• Highlighted (only for "...MontageChannel" groups)
• SelectedHighlighted (only for "...MontageChannel" groups)

The "..._Selected" sub selection indicates colour setting for colour of highlight of channel in Montage editor (while channel is selected in channel list).

The "..._Highligthed" and "..._SelectedHighlighted" indicate colour setting for channel selection by mouse hover or selection respectively in Montage editor topographical view.

Note that this setting is only possible for special groups "...MontageChannel".

The colour values are given in [RED,GREEN,BLUE] triples, each value may range from 0 (weakest intensity) to 255 (maximum intensity). For internal reasons, the "ColText..." and "ColPlot..." colours must not be deep black (000,000,000). If a black colour should be set, use a colour close to black (see line ColTextPolygraficChannel=000,000,001). The difference will not be visible.

Note that the configuration file is written when the program is closed. So do not change it while BESA Research is open. Otherwise, your changes will be lost at program termination.

The example of colour settings (the colour triples show the default values):
