What sort of scanner do you have?  Is there any spectroscopy data among your DICOM files?

DICOM is an extremely complicated file format (there are well over 1000 of the most tedious pages of documentation imaginable for the simplest and most straightforward version of DICOM), and scanner manufacturers also have their own modifications to the format, which is often not documented.  Other than buying a new scanner, I would suggest trying some of the other DICOM conversion utilities that are out there.

I have no intention of becoming a professional DICOM expert, but (providing there are no confidentiality issues – remember there is a lot of identifying information in the headers) I could have a quick look at ONE of your DICOM files if you email it to me.  Maybe there is a quick fix I could make in order to get the SPM conversion to deal with your data.

Best regards,

Subject: [SPM] dicom import in spm5

dear spm list,

i have trouble with dicom import in spm 5.

if i select the .dcm files, the output directory, and the default conversion options (single image and  icedims 'no')

I get the following error

Initialising SPM.........done

in terms of troubleshooting i have done the rather inelegant option of trying all combinations of conversion options, on two different computers each with different versions of matlab, before and after
running SPM_update. so i conclude i am doing something really basic wrong, but i dont know what.

any help would be greatly appreciated,

best wishes
