dcmj2pnm protests, but not dcmdump

[st80rules]

Hi,

I'm having a hard time opening a given DICOM image, and trying to figure out why is sort of an ordeal.

Dcmdump doesn't report much, the only oddity I see is this:
...
(0002,0001) OB 30\31 # 2, 1 FileMetaInformationVersion
W: DcmUniqueIdentifier: Element MediaStorageSOPClassUID (0002,0002) contains one or more space characters, which were removed
(0002,0002) UI =SecondaryCaptureImageStorage # 26, 1 MediaStorageSOPClassUID
...

dcmj2pnm says this:
E: can't change to unencapsulated representation for pixel data
E: can't determine 'PhotometricInterpretation' of decompressed image
E: can't convert input pixel data, probably unsupported compression
F: Invalid DICOM image

while in my code using the DicomImage class all I get is "Invalid element value".

Below is the entire dcmdump.

Can anyone point me out to what's wrong?

OK never mind, after more digging I found that dcmtk doesn't support the YBR_RCT photometric interpretation, and I've managed to work around that.

The real reason is that dcmj2pnm does not support JPEG2000 compression. Reading the documentation would help - as always
