Greetings:
I need to read in a DICOM image. This obviously is trivial but I am
hung up on getting the path set correctly. I am using IDL V6 on Mac OS
X and X11. The file I want to open is
/Volumes/A/00130.DCM
I am trying to open it using the following:
Pro testdicom
img = READ_DICOM(FILEPATH('00130.DCM', SUBDIR=['Volumes', 'A']))
tvscl, img
end
and I get the following error message:
READ_DICOM: The file /usr/local/rsi/idl_6.0/Volumes/A/00130.DCM is not
in a supported DICOM format.
I have fooled around with !PATH, the preferences, openr, etc.
I want to avoid moving the file to /usr/local/rsi/idl_6.0 because of
its root privileges and invisibility.
OK, so what do I need to do to set the correct path?
Thanks

using the help, /dlm after starting I get the following, (edited)
** PFGENLIB - Interface of IDL with Patrick Ford's code (not loaded)
Version: 1.0, Build Date: JULY 2003, Source: Ronn Kling
Path: /Volumes/A/IDLtoPFgenLib.so
the others have the following path:
Path: /usr/local/rsi/idl_6.0/bin/bin.darwin.ppc/filen_name

It is not the external code because it was working dandy prior to my
fiddling around trying to get the DICOM file read and I got the DLM
guru to do this for me. I have kludged it by putting copies into the
path that it has,but I would really like to know what I did and how to
fix it.
Thanks.
