Dear SPM users, I am new to SPM and am trying to learn the software since I believe it has a very good potential in assisting me with my research. Unfortunately, it doesn't seem to work. When I try Epoching or Artifact, on the data I found on the SPM site (multi-modal faces) I get the following error: New working directory: /home/Adam/Documents/MATLAB/Multi-modal faces/EEG ----------------------------------------- 13:22:02 - 07/01/2009 checkmeeg: sampling rate is missing ??? Error using ==> spm_eeg_artefact at 58 Trouble reading file /home/Adam/Documents/MATLAB/Multi-modal faces/EEG/e_eeg.mat ??? Error while evaluating uicontrol Callback checkmeeg: sampling rate is missing ??? Error using ==> spm_eeg_epochs at 55 Trouble reading file /home/Adam/Documents/MATLAB/Multi-modal faces/EEG/e_eeg.mat ??? Error while evaluating uicontrol Callback I get the same error on other data sets as well. I suspect it is a global problem since it affects a few functions and not only one. I use Ubuntu 8.04.1 and Matlab 7.6.0(R2008a) Thanks for your help, Adam
