Hi Benjamin:
If you are missing the Sess field I wonder if you are using 2nd level data? DCM must be done on
first level (time series) fMRI (or ERP) data. It can then be combined across subjects.

I am specifying a DCM and after selecting my VOI's for the DCM I receive
following error in the command window:

Creating the VOI's from the SPM.mat file proceeds normally and the files
are written to the appropriate directory.
I am using SPM5 (rev 958) on an Intel MAC running 10.4.11 in Matlab 7.4
Can anyone tell me what might be going on?
many thanks,
