[FieldTrip] Is it a bug for ft_spike* functions or something wrong with my data?

[Jing Wang]

Hello Eelke,

Thank you very much for your answers. I will file this bug in Bugzilla
tracking system.

I also found that there are some functions which are used in the ft_spike*
function are not in the Fieldtrip. One is *specest_nanfft.m* which is used
in ft_spiketriggeredspectrum.m and another is *ft_write_spike* which is
used in ft_spikedetection. We could not find the two functions in Fieldtrip
to run these main functions about spike analysis.

Whether it has been changed names or  put somewhere else? Would you please
give me some idea about that?
Thanks again!

Best Regards

Jing
