[CWB] Key specification

If your alignment file uses keys e.g. of the form "filename_1" (for the sentence above), then the key specification in the first line of the alignment file should read

SOURCE_CORPUS	TARGET_CORPUS	s	{file_id}_{num}

A very similar example can be found in the online help ("perldoc cwb-align-import"), at least if you have installed a recent version of the tool from the SVN repository.
