File Formats Map

The map file is a comma-separated-values file with the location of each spectrum and the percents of each element in columns, with each spectrum on a separate line. The location information is precisely as read from the spectrum data file. The first line is a title from the spectrum file or the first spectrum file name. The second line is a list of the column headings including the element symbols for any element percent columns. The final columns may contain some diagnostic information, such as the goodness-of-fit parameter (reduced chi squared), to help distinguish any poorly-quantified spectra. This is an example of a simple map file produced by PIQUANT.
