[FieldTrip] head movement correction creates complex values => why

[Conny Quaedflieg]

Dear users, 

 

With regard to my question, why the data from 12 out of 70 participants ta
(e.g.,powerspctrm) contains complex values after using ft_regressconfound, 

I found out that the circumcenter is causing the complex single values.
Though don’t get it why they become complex 

 

I attached coil positions of 2 pp’s 

Vp22 gets complex values 

The circumcenter function is also attached. 

This is what I run: 

 

cc = circumcenter2(coil1, coil2, coil3);

 

or for PP 22

 

cc_vp22 = circumcenter2(coil1_VP22, coil2_VP22, coil3_VP22);

 

 

Maybe someone sees why they become complex and can tell me how to solve this
:) 

 

Thanks in advance

Conny

 

 

 

 

 

 

 

 

 

Mit freundlichen Grüßen,
