Thanks Francois!
Flipping the sign of the Z coordinate in the text file worked a treat.
Another question. I'm importing some custom, individualised parcellations from freesurfer so that I can extract time series from them. I've followed the instructions in the link below, but would like some advice on the best order to do this:
Is it best to:
- import the new L + R pial surfaces and custom parcellations, downsample to 7500V to match the low resolution surfaces, merge them and set this new cortex as the 'default surface' before computing the head models; or
- generate the headmodels using the original surfaces and then project the sources to the imported surfaces containing the desired custom parcellations afterwards.
My intuition is that they should be identical, although (1) could save time . Thoughts?
Cheers,
Nigel
