Hi everyone
I need to import EEG coordinates (obtained with
Polhemus system in ASCII format)
in the FreeSurfer workspace. My final aim is
characterize small areas of the cortical surface
(exactly the regions underlaying my sensors position)
with typical parameters of FreeSurfer (cortical
thikness,...) .
I have read some papers reporting partial solutions to
my needs. All of them used matlab with some exported
files of FreeSurfer and registered them with the
coordinates of the EEG or MEG analysis. I will like to
have an opposite solution: import the file with the
coordinates of the EEG into the FreeSufer workspace,
maybe using the Load/overlay /registration menu of
FreeSurfer or another that you can suggest me.
I guess my coordinates file needs some transformations
before import it to the FreeSurfer workspace
thanks in advance
abel
