Thanks, but our problem was rather “boring”- a bad naming scheme of Siemens:
“For Siemens users who get “_Eq” images: this occurs because Siemens scanners can generate the same series (0020,0011) and instance (0020,0013) number for the same slice acquired for two echoes.” (Prof. Rorden)
, together with some script handling duplicated data…
Anyhow- all the information is here:
WE MIGHT HAVE MISSED THE PROBLEM (IF WE WERE USING A DIFFERENT NIFTI CONVERSION TOOL)- IT WAS NOTICED ONLY AFTER A DCM2NIIX WARNING APPEARED DURING CONVERSION!
BTW, do you have any recommendations regarding the time difference between a field map scan and the matching bold data?
or- how “stable” is the field (I can test our data, but I’m wondering if some general advise exists…)
Many thanks
