Dear Bennett Landman

Everything looks ok after running BPMe_3.0 robust correlation module in SPM8 with Matlab R2010.
I have some further questions and problems when i play with Model II regression and hope you could give me a hand:

1. What is "predefined prior " and how could i get or calculate this predefined prior for Model II regression ?

2. The manual mentioned that if i don't have a "predefined prior " for Model II regression , i need to specify the window size for the main modality image and regressor image respectively. Could you give some hints for identify these values for each image modality respectively ?

3. Currently i follow the manual to play with the function of Model II regression, after setting all the parameters, i get following error:

Dimension of Priors does not match
??? Attempted to access prior_mu(1); index out of bounds because numel(prior_mu)=0.

Error in ==> modelII_bpm_glm at 59
mu(i,1) = prior_mu(i);
Error in ==> modelII_bpm_ancova at 336
[beta_coef,XX,dof(:,:,slice_no),sig2(:,:,slice_no),Es] =
modelII_bpm_glm(data,confound,col_conf,brain_mask(:,:,slice_no),ngsubj,beta_coef,E,sig2_slice,dof_slice,XX_slice,mu,fmuimg);
Error in ==> wfu_bpm_execute at 43
[X,dof,sig2,mask,nsubj,nr,Vtemp] = modelII_bpm_ancova(BPM);

[results] = wfu_bpm_execute(BPM);
Error in ==> wfu_bpm>button1Callback at 188
wfu_bpm_analysis;
??? Error while evaluating uicontrol Callback

Sorry to bother you and thanks for your kindly help.

PS: I use Matlab R2010a with SPM8 and Mac OSX 10.8.2

Best
