[FieldTrip] ft_determine_coordsys does not return coordinate system

[Thomas Radman]

Hello,



I would like to use individual MRIs to perform source analysis on EEG
data.


The problem I have is when importing dicoms into fieldtrip, and then using
ft_determine_coordsys, the coordinate system is not returned.  How can I
determine the coordinate system and align this to my EEG sensors?


Also, to use ft_volumerealign in interactive mode to select fiducials I
need to know which side is right and which is left.  Is it possible to do
this if I did not have a vitamin E marker in my scans?


Thank you,

Tom Radman
