Fiber files (*.fbr) created with TrackMark ("TM") have a slightly different format than fiber files generated with BrainVoyager ("BV"). In order to import TrackMark fiber files into BV, a minor change has to be applied to the TM fiber file.
Open the TM fiber file in a text editor. The first lines are, where NrOfGroups can be an arbitrary number:
FileVersion: 3
CoordsType: BVI
NrOfGroups: 11
This has to be changed into (watch the empty line between FibersOriginZ and NrOfGroups):
FileVersion: 4
CoordsType: BVI
FibersOriginX: 128
FibersOriginY: 128
FibersOriginZ: 96
NrOfGroups: 11
Next, change each Name field, by adding quotes "<fiber group name> " to each Name field, ie
Name: TPA tracking from VOI A converts into Name: "TPA tracking from VOI A"
save the fiber file, and import it into BV via the DTI > Load Fibers command.
