The problem occurs (probably among others) on line 330 in ft_read_header. Explicitly specifying 'ctf_old' for dataformat and headerformat seems to work fine.

Changed the status of bugs without a specific owner to UNCONFIRMED. I'll try to replicate these bugs (potentially involving the submitter), and change confirmed bugs to NEW. Boris

Could you give an example script and data?

Well, we would need to record some data without meg-channels, which I think is an overkill for this bug. Acquiring a dataset in the MEG without specifying MEG channels to be recorded is unusual usage of the MEG system so I wouldn't spend too much time on reproducing and creating a fix. Particularly if specifying cfg.dataformat = 'ctf_old' works.
