Hi Ram,
If you provide sufficient information on the command line, and
if you provide the -prefix option, then no GUI will be opened.
If you are starting with I-files or DICOM files, then to3d can
get a lot of information from those headers. What are you
starting with? And are you talking about anatomical data, or
EPI?
Note that once a single dataset is created, then it can be used
as a -geomparent for the data grid.
