| Arguments | <locus file name> [notrait] . |
Read locus names, types from a PLINK format locus (.map) file. The notrait modifier stops a dummy binary trait being declared as the first locus.
A PLINK style locus file contains one record per locus, the first four fields being:
| chromosome: number, X, Y (or 0 if unplaced) |
| marker name |
| Genetic distance from map start in morgans (or Mbp) |
| Physical distance from map start in base pairs |
Example:
>> read locus plink test.map Read in names of 3 loci from locus file.
