[FieldTrip] MNE fiff_read / write_raw_segment

Hi Fieldtrip list,

I'm trying to add an altered channel and save it as a new fiff file using the MNE commands from the external/MNE dir in Fieldtrip, but seem to just keep getting the data from the old fiff file instead.

The code I'm currently using is:

To read:
fh = fiff_setup_read_raw('input.fif');
f = fiff_read_raw_segment(fh);

After adding in the altered channel data to f, I then use:

fiff_write_raw_segment(output.fif, fh);

What I thought would happen is output.fif would use the information in f and fh to write output.fif, but what seems to be happening is the data in f is being ignored.

Does anyone have any ideas on how to insert the altered channel data then write it back out as a fiff file?
