All of the programs print the message
Warning: no data dictionary loaded, check environment variable: DCMDICTPATH
then seem to produce strange results.
The DICOM data dictionary could not be loaded. It has probably not been properly installed. The default location for this file (under Unix) is "/usr/local/dicom/lib/dicom.dic" but an alternive location can be specified by using the DCMDICTPATH environment variable. See the documentation file "dcmtk/dcmdata/doc/datadict.txt" for more details about using DICOM data dictionaries.
