Converting DOS CANTAB STM files

In MonkeyCantab's installation directory (usually C:\Program Files\MonkeyCantab) there's a Perl script called convert_stm_to_monkeycantab_xml.pl.

This reads old DOS CANTAB stimulus (STM) files, which encode Cambridge Cognition "quad pattern" stimuli, and produces an XML file legible by MonkeyCantab, so you can import your old stimuli.

To use this, download and install Perl 5.10 or higher (e.g. from ActiveState). Run the Perl script from the command line. Specify the input (something.stm) and output (something.xml) files.
