When head surface points and/or EEG sensor locations are measured using [https://polhemus.com/scanning-digitizing/digitizing-products/ Polhemus Fastrak] device together with [https://cortechsolutions.com/products/emse/software/locator/ ''Locator''] software or [https://neuroimage.usc.edu/brainstorm/Tutorials/TutDigitize ''Brainstorm Digitize''], the digitized points can be exported to a file format compatible with BESA Research (e.g. [http://wiki.besa.de/index.php?title=Working_With_Additional_Files#sfp_.28surface_point_coordinate.29_file *.sfp]). On the other hand, if you are using ''PiMgr'' software (Polhemus tracker management application), you need to reorganize the digitized surface points to fit the file format BESA Research requires. The following wiki article describes how to reorganize digitized surface points for BESA Research: [http://wiki.besa.de/index.php?title=Electrodes_and_Surface_Locations#Polhemus_Digitizer_Data Electrodes and Surface Locations | Polhemus Digitizer Data]

After the reorganization, digitized surface points can be imported to BESA Research using the ''Channel and digitized head surface point information'' dialog (''File → Head Surface Points and Sensors → Load Coordinate Files...'', keyboard shortcut: CTRL + L). See also the following wiki article: [http://wiki.besa.de/index.php?title=Importing_Digitized_Coordinates Importing Digitized Coordinates]

The imported digitized surface points can be inspected in a 3D view using the menu ''File → Head Surface Points and Sensors | View'' (keyboard shortcut: V).
