Hi Dan,
No such information is imported from the DICOM files.
However the HISTORY note contains the command that
was run to generate the dataset, along with the user name
and date. If the names of the DICOM files contain the
subject name, then they will appear in the HISTORY.
Just check the output of "3dinfo" to see what is there.
If desired, the HISTORY can be removed using '3drefit -denote'.
