% datasets_config Defines locations of datasets
%
% This m-file interacts with a <a href="matlab:help prstnt_struct">persistent structure</a>
% and stores information about the structure in which the datasets are
% stored on the filesystem. Inside those, one can use variable
% substitution. A list of substituted variables is available in
% <a href="matlab:help strrep_variables">strrep_variables</a>.
% 
% For each dataset, datasets_config shall initialise to nan the following
% four configuration variables:
%
% DATASET_basedir   the root directory for this dataset
% DATASET_subdir    directory in which files are stored
% DATASET_regexp    regular expression matching filename; should have some
%                   named matches to get year, month, day, etc.
% DATASET_filename  if possible, set to calculate the filename directly
%                   from year, month, day, etc.
%
% To set actual values, add datasets_init to your path. This is executed
% when datasets_config is run for the first time.
% For example settings, see site-specific/kiruna/datasets_init.m. If adding
% a new dataset, it is recommended to also set defaults in the
% site-specific initialisation, so that others can use it directly and that
% it can serve as an example to people at other sites.
