I haven’t had a chance to look at those new files, so I’d be interested to hear more about your experience.
If you’re not familiar with it, you should check out https://github.com/CMRR-C2P/MB/blob/master/readCMRRPhysio.m . One thing to note, at least with the legacy files, the time stamp in the DICOM corresponds to the onset of the “dummy scans”: scans used for the SBRef plus dropped scans for T1 equilibration. In HCP data, those dummy scans corresponded to 13 TRs (MB8 -> 8 TRs for SBRef, plus 5 TRs for dropped scans). It would be interesting to see if ACQ_START_TICS corresponds to some number of TRs after the time stamp in the image DICOM header. In the legacy files, there were timestamps in each modality that corresponded to the ms clock time of the PMU. If you’re getting different clock times for different modalities, they might correspond to these. (Although I thought the point of the ICE logging was to eliminate reliance on the PMU times.) --Greg ____________________________________________________________________ Greg Burgess, Ph.D. Staff Scientist, Human Connectome Project Washington University School of Medicine Department of Psychiatry Phone: 314-362-7864 Email: gburg...@wustl.edu > On Oct 6, 2016, at 10:07 AM, Andrew Bock <bock.and...@gmail.com> wrote: > > Hi all, > > Has anyone had issues with the "new" format of the physio files, which end in > PULS.log?
