using reference gradiometers with preproc_denoise

[Mark Drakesmith]

Hi

I am just looking over some MEG data and was wondering what is the best
way of dealing with noise. the 4D MEG scanner includes 11 reference
coils for detecting noise within the MSR. What is the best way of using
this for data-cleaning? I am currently using preproc_denoise to do this,
but the description suggests it should be used when continuous head
motion channels are used, which is not the case here. Is it appropriate
to use preproc_denoise or should I be using an ICA-type approach?

Any help clearing up this confusion would be greatly appreciated.

Regards

Mark
