To make these function work under the EEGLAB interface you must uncompress the ctf folder in the plugin directory of EEGLAB. Type cd eeglab4.311/plugins cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/eeg checkout ctf [use "move" instead of "mv" under windows] What these commands do is that they download all the files into a folder named ctf under the plugin sub-directory of your version of EEGLAB.
