Description

The LoadAscii algorithm reads in spectra data from a text file and stores it in a Workspace2D as data points. The data in the file must be organized in columns separated by commas, tabs, spaces, colons or semicolons. Only one separator type can be used throughout the file. Use "Separator" property to tell the algorithm which separator to use. The columns can contain X, Y ot error values. The first column in the file has to have the X values which are common for all spectra in the file. The X column is followed by pairs of of columns containing Y and error values. For a workspace of n specrta there must be 2n+1 column in the data file.
