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" for ordinary comma separated values ascii text files
• ".blkcsv" for comma separated value ascii text files in block format
• ".bin" for binary files in block format

".csv" files may contain 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 single file containing the actual data where that file must have a commented line containing the column header. Co-variance matrices must be supplied as full squared symmetric matrices.
