The stream samples file contains the measured concentration and analytical uncertainty of all tracers for all stream samples. The file starts with an integer value signaling the amount of samples in the file. The next line is the header, and must contain Sample - Datetime as the first two columns (tab-separated). Further columns contain each solute and the analytical standard deviation of each solute. All further lines contain the corresponding tab-separated values for the samples. Format of the datetime column is unicode format: yyyy-mm-ddThh:mm:ss (not necessary for G-EMMA, but read by the Python module). Comment lines start with an !.
