Note that, as Tibor experienced in that thread, some DICOM servers mangle the necessary fields for calculating echo spacing, because they aren't defined in their DICOM dictionaries.
If that is the case for you, email me and I can forward you the mechanism that I worked out with Tibor to convert the mangled hex values via matlab.
cheers,

To: [log in to unmask]Dear FSL Community,
I was wondering if anybody had experience with B0 unwarping on Siemans scanners. Is it possible to extract the Effective EPI echo spacing and the echo time difference of the fieldmap sequence from the SIEMENS headers?
Kind regards,
- Charles
