[FieldTrip] Creating a New CTF Ds file

[Schoffelen, J.M. (Jan Mathijs)]

Hi Luke,

No, FieldTrip does not allow for this ‘reverse' writing of the CTF format. Out of curiosity, is there a particular reason why you would want to do that? You could check the low-level ctf code that comes shipped with fieldtrip (in external/ctf/), there are a bunch of functions that start with write*. Reverse-engineering all this is probably possible (I would start with a low-level description of the data that is outputted as a structure by readCTFds.m. My hunch would be that the MATLAB-representation of the data should be in the exact same format to make it writeable.

Best,
Jan-Mathijs

Hi,

Is anyone aware of any tools for writing CTF DS files out from fieldtrip data structures?

I see that it isn't listed as an option for ft_write_data (http://www.fieldtriptoolbox.org/faq/how_can_i_convert_one_dataformat_into_an_other) but perhaps others have already dealt with this issue?

Thanks
Luke
