dcm2niix slice time correction
Hello,
I am running dcm2bids, which calls dcm2niix during the process. I've been seeing some conflicting statements regarding whether or not dcm2niix automatically performs slice timing correction. Is this the case, and if so, can it also account for multiband slice acquisition?

RE: dcm2niix slice time correction
dcm2niix does not correct for slice timing. If it is able to
determine the slice times, they are reported in the BIDS
'SliceTiming' tag. It will also try to set the slice_code tag of
the NIfTI header, though this tag predates multiband imaging and
therefore it is unable to specify all possible acquisition schemes.
You can use the contents of either of these tags to perform using
your favorite tool (e.g. SPM or FSL's slicetimer). As a rule,
dcm2niix tries to provide the raw DICOM data with as little
manipulation as possible. My notes on slice timing are
