Hi Colm,
Yes, the orientation should be deduced from the information in the
header of the DICOM file.
If you are converting single slice image files into AFNI BRIKs,
then perhaps Dimon can even help with the timing info:
Dimon -infile_prefix run2/image -dicom_org -GERT_Reco -quit
In that example, your EPI image files are in the run2 directory,
and they all start with the string 'image' (maybe ending in .ima,
maybe not).
See "Dimon -help" for more information and examples.
