As the name implies, a Tarsier Raster Data file (.tra) is Tarsier's gridded data format. It is made up of two parts: 1) an ASCII header file that specifies the structure of the grid and data properties, and 2) a series of data values stored in binary.
A typical Tarsier header looks like:

Rows 25
XLLCorner 0

CellWidth 1
CellHeight 1
NoDataValue -9999.000000
