title: Siemens DICOM Individual Slice Time (Private_1019_1029)
body: <p>I'm seeing that the individual slice time information from the <code>Private_0019_1029</code> field of the DICOM header has negative values and sometime only positive values.<br/>
  I assumed that these times are with respect to the Volume Acquisition time recorded in the header.</p>
  
  <p>Going by that assumption, it would mean that the Acquisition time varies.  But upon checking the difference between successive volume acquisition times, I see that it's equal to TR.<br/>
  So I'm at a loss about what's happening.<br/>
  I'm trying to look at the raw fMRI data without slice time correction; hence it's necessary to have the individual slice times.</p>
