Hi experts, 

When I conducted group inversion of source reconstruction for my EEG data in SPM, I got hundreds of warning messages, as shown below. 

Could you tell me what’s wrong with my inversion? Could you tell me how to fix them?


SPM12: spm_eeg_inv_forward (v7702)                 3:23:13 - 23/08/2022 


reading 'headmodel' from file 'N:\ spm12\canonical\single_subj_T1_EEG_BEM.mat' 

Warning: use cfg.sourcemodel instead of cfg.grid  

creating sourcemodel based on user specified dipole positions 

8195 dipoles inside, 0 dipoles outside brain 

Completed                               :          3:24:13 - 23/08/2022 

Thank you very much!
