Hi everyone!
I hope everybody is ok!
I'm trying to compute sources from an EEG file and to display it on a MRI volume, but when I tried it, Bs gave me this message:
BST> Emptying temporary directory...
BST> Emptying temporary directory...
BST> process_timefreq: Using 1 windows of 256 samples each
WARNING: Some dipoles are outside the BEM layers (39 dipoles).
The leadfield for these dipoles is probably incorrect.
Here is the pipeline I used:
first I loaded the neuroscan cnt file with "Review raw file" option,
I add eeg positions --> ICBM152 --> Generic --> 10-20 ASA 94
then I split the continous file in many 1 second epochs
I selected No noise Covariance (is a resting state file with no previous conditions)
Then I computed Head model
MRI volume
Scalp 1082 vertices: 1
Skull 642 verices : 0.0125
Brain: 642 vertices: 1
Use adaptative integration
Regular Grid (Isotropic)
I was able to compute sources for cortex displaying, but no for mri volume
What am I doing wrong?
How can I prevent dipoles to be outside head?
Note: the EEG was made with just the 19 10-20 electrodes
Thanks in advance!
