Dear all,

I encounter a problem when trying to export with MlwiN a column as a .txt file ; I've got the following error message: "cannot open or close file (DWRI)"
Has anybody an idea about the way this problem could be solved ?

Best regards,
Arno.

This message usually indicates that MLwiN has encountered a problem creating the file in the chosen directory, this could happen for example if the location where you chose to save to was read-only or didn't exist. You could check this by choosing a location with the browse button that is definitely accesible to you, such as your documents folder.
