function writeIngrepen(OPT,ingrepen)
%WRITEINGREPEN  Write all ingrepen series to the file
%
%   The ingrepen are written to the file. There is a column for each series
%   type, preceded with the time string.
%
%   Syntax:
%   writeIngrepen(file,ingrepen)
%
%   Input:
%   file     = the name of the file where the series values are written, it is
%              a text file with columns seperated by spaces.
%   ingrepen = the structured variable with the ingrepen series values,
%              created in Westerschelde_ingrepen.m with a call to 
%              computeIngrepen.m
