Input files

File content determination via file name extensions

lmt automatically detects the format of input files by the filename extension. Supported extensions are

".csv" files may contain several commented lines at the top only where the comment character is "#".

The type of the file content is determined by its prospective use, that is

the data file is supposed to contain only real/float numbers which are transferred to integer if required,
a file containing an ordinary pedigree is supposed to contain only integer numbers,
a file containing a missing value indicator matrix is supposed to contain only character strings.

lmt accepts only a single file containing the actual data. A data file in ".csv" format must follow the following formatting rules:

file must have at least one commented line where the last commented line must containing the column names separated by comma,
the column names
- must be alpha-numeric only
- must not be quoted
- must be unique
below the header the data file must contain only numeric values where the decimal separator is a dot(".").

An example for a data file with three columns is shown below.

#y,mu,id
25.0,1,5
33.1,1,6
36.0,1,7
28.3,1,8

Co-variance matrix files contain full squared symmetric matrices, for instance

1.5,0.8,0.1
0.8,2.1,1.1
0.1,1.1,1.9
