crimap documentation (version 2.4)


4. File structures

CRI-MAP uses four different types of files. These all have names of the form chrx.y, where x is the chromosome "number" and the suffix .y is one of

.gen
the raw genotype data file
.par
the parameter file
.dat
the processed data file
.ord
the orders file, or "orders database"

The user must supply the .gen file. The .dat and .par files are created using the option prepare, and must be constructed before using any other CRI-MAP options (except merge ). The .ord file is initialized by prepare, but required only for the map building options (build, instant, and quick ). You will need to learn about the structures of the .gen and .par files, but can ignore the descriptions of the other file types if you wish. Each file is in ASCII format, and can be edited with a text editor. For readability, the user can insert additional blank or end of line characters into these files if desired, since the C statements which read the files treat any string of such characters as a single "white space" delimiter between data items. All data items are either numbers or character strings containing no blank spaces; they must be separated by white space delimiters. In the following descriptions, brackets {} are used to enclose data items appearing in the file but do not themselves appear in the file.
