Source reconstruction questions
- Can I do combined EEG and MEG source reconstruction?
- Can I restrict the source reconstruction to the grey matter?
- How are electrodes, magnetometers or gradiometers described?
- How are the different head and MRI coordinate systems defined?
- How are the Left and Right Pre-Auricular (LPA and RPA) points defined?
- How can I check whether the grid that I have is aligned to the segmented volume and to the sensor gradiometer?
- How can I convert an anatomical MRI from DICOM into CTF format?
- How can I determine the anatomical label of a source or electrode?
- How can I fine-tune my BEM volume conduction model?
- How can I map source locations onto an anatomical label in an atlas?
- How can I visualize the different geometrical objects that are needed for forward and inverse computations?
- How do homogenous coordinate transformation matrices work?
- How do I install the OpenMEEG binaries
- How is anatomical, functional or statistical "volume data" described?
- How is the segmentation defined?
- How should I report the positions of the fiducial points on the head?
- How should I specify the fiducials for electrode realignment?
- How to change the MRI orientation, the voxel size or the field-of-view?
- How to coregister an anatomical MRI with the gradiometer or electrode positions?
- Is it good or bad to have dipole locations outside of the brain for which the source reconstruction is computed?
- Is it important to have accurate measurements of electrode locations for EEG source reconstruction?
- Is it OK for vertices/dipoles to stick out of the volume conductor?
- My MRI is upside down, is this a problem?
- Should I use a Polhemus or a Structure Sensor to record electrode positions?
- What is the conductivity of the brain, CSF, skull and skin tissue?
- What is the difference between the ACPC, MNI, SPM and TAL coordinate systems?
- What kind of volume conduction models of the head (head models) are implemented?
- What material is used for the flexible MEG headcasts?
- Where can I find the dipoli command-line executable?
- Where is the anterior commissure?
- Why does my EEG headmodel look funny?
- Why is the source model deformed or incorrectly aligned after warping template?
- Why is there a rim around the brain for which the source reconstruction is not computed?
- Why should I use an average reference for EEG source reconstruction?
