Ok James, no worries. See Velu's reply and click the link.

You need to modify this code by adding the following lines maybe after line
145.

case 250
[B,A] = deal([Hyeonseok's values here]);

Then save the .m file.
This updates your clean_rawdata() so that it applies the precalculated
filter for the datasets sampled at 250 Hz when the Matlab toolbox is
missing.
