: Verify that the head model and sensor array use the same coordinate system (e.g., MNI or CTF).
: Use the "3D Source Reconstruction" button to load your head model. Ensure your structural MRI and sensor locations (fiducials) are coregistered, as mismatches can lead to scaling errors where the head appears smaller than the sensor helmet. HM_SPM.rar
: If running a surface analysis, check for errors where covariate dimensions (like realignment parameters) do not match the number of functional scans. : Verify that the head model and sensor
: If importing preprocessed SPM data, use the in_fopen_spm function. Note that epoched data might require custom scripts to correctly map channel information from raw files. 3. Troubleshooting "Piece" Preparation : If running a surface analysis, check for
