Hi Xinman,

According to the first error message, the Sequence Name in the DICOM header does not contain 'ep'. Do you know the name of the pulse sequence that was used to obtain the DICOM images? Was it an EPI pulse sequence?

Normally the "combined" folder gets created during the DICOM-to-NIfTI conversion. However, that conversion was stopped because of the first error (the sequence name doesn't contain 'ep'). Since the conversion was stopped, the "combined" folder didn't get created, and no "rdki" file got created, leading to the second error message.

Best,
Dave
