[MINC-users] errors going from DICOM startxyz to MINC startxyz

[Audette, Michel]

Hi folks,

I'm frantically trying to meet a conference paper deadline, and have it a snag. 

I have some expert validation data for anatomical boundaries, which come in stl format, and these have been produced with a software called Mimics from Dicom. Looking at these stls, the vertex coordinates do not coincide with the reasonable world coordinates in the minc file that I'm getting after doing dicom3_to_minc, and resampling with positive xyz. The start x,y,z of the minc volume also bears little resemblance to image position patient (0020-0037) visible under Image Position Patient. 

Can anyone suggest a way of reconciling Dicom with minc start x,y,z, to begin with? 

Cheers,

Michel
