+# this script creates transcode a DICOM file with all types of compression.

+# it creates one study per compression type

+#

+# note: it has been tested only  only on Windows: you would probably just need to update dcmodify into ./dcmodify and gdcmconv into ./gdcmconv to make it work on Linux

+# prerequisites:

+# you must have DCMTK installed and in your path [http://dicom.offis.de/dcmtk.php.en]

+# you must have GDCM installed and in your path [https://github.com/malaterre/GDCM/releases]
