Dear Christiano,

This has only recently been implemented and is now being tested at
FCDC. Look at denoise_synthetic function. You will also need to
download the ctf toolbox from
ftp://ftp.fcdonders.nl/pub/fieldtrip/external/ctf.zip and specify
'ctf_new'  as filetype when you read the data (in particular the
header with grad). But keep in mind that this is still very
experimental.

Good luck,

Vladimir
