Hello all,

After completing a series of large fMRI analysis (analyses were specified and estimated) in SPM2, I was not able to access some of the results, getting the following error message when I attempted to call up the SPM.mat file:

>??? Reference to non-existent field 'xVol'.
> >Error in ==> /home/ndplab/spm2/spm_getSPM.m
> >On line 163  ==> XYZ    =
SPM.xVol.XYZ;                
%-XYZ coordinates
> >Error in ==> /home/ndplab/spm2/spm_results_ui.m
> >On line 260  ==> [SPM,xSPM] = spm_getSPM;
> >??? Error while evaluating uicontrol Callback.

This error was posted on the list before: http://www.jiscmail.ac.uk/cgi-bin/wa.exe?A2=ind03&L=spm&P=R4115&I=-1
with the only known solution at that time being to re-do (estimate) the analysis. Has anyone figured out why the error occurs and how to prevent it? Is there a way of accessing the results of an analysis in which this error message occurs other than re-estimating? As noted in the above post, I found this problem to be intermittent in a series of very similar analyses. Any ideas toward a solution, in whole or in part, will be much appreciated.

Thanks in advance.

Best regards,
Brandall
