% Get/set the defaults values associated with an identifier
% FORMAT defval = cg_vbm_get_defaults(defstr)
% Return the defaults value associated with identifier "defstr". 
% Currently, this is a '.' subscript reference into the global  
% "defaults" variable defined in spm_defaults.m.
%
% FORMAT cg_vbm_get_defaults(defstr, defval)
% Sets the vbm value associated with identifier "defstr". The new
% vbm value applies immediately to:
% * new modules in batch jobs
% * modules in batch jobs that have not been saved yet
% This value will not be saved for future sessions of SPM. To make
% persistent changes, edit cg_vbm_defaults.m.
