+SaveANSTOAscii is an export-only Acii-based save format with no associated loader. It is based on a python script by Maximilian Skoda, written for the ISIS Reflectometry GUI
 ==== Limitations ====
-
+While Files saved with SaveANSTOAscii can be loaded back into mantid using LoadAscii, the resulting workspaces won't be usful as the data written by SaveANSTOAscii is not in the normal X,Y,E,DX format.
