GOLD - Map File Format

The map file describes the physical location of markers. It has the following format:

MARKERID   NAME      LOCATION
<col1>     <name1>   <bp1>
...
<colN>     <nameN>   <bpN>

After the single header line, each line describes a single marker. <col1> indicates the location of the marker in the pedigree file (1 is the first marker on each line, and so on), <name> is the markers name (without spaces), and <bp> is the markers location on the physical map, in base pairs. If simwalk2 is used for haplotype estimation marker names should be no more than 8 characters long.

An example map file describing three markers would be:

MARKERID   NAME      LOCATION
       1   DCP1-G/C  8349
       2   DCP1-A/T  8777
       3   DCP1-A/C  9539
