An example of a .puls logfile is given below. The data are stored in one long line. The text contained between 5002 and 6002 forms the header, and the text between 5003 and 6003 the footer. Important information in the footer is the LogStartMDHTime and the LogStopMDHTime (in ms since midnight), which can be used to synchronize the logfiles with the dicom images using the AcquisitionTime in the dicom header (in hhmmss.ms). The values 5000 and 6000 are inserted into the signal trace and indicate trigger events. Note that only the modality which is selected to be displayed during the acquisition will have triggers.

## CMRR Sequence
|
|
|
|
|
|
The CMRR sequence on VD/VE also allows the automatic recording of physiological log files (to be selected in the sequence special card). For more information have a look at the [manual](https://www.cmrr.umn.edu/multiband/). There were a few iterations, an example of the current format (December 2017, Release 016a) is given below. The physiological traces are stored in logFileName_PULS.log, logFileName_RESP, logFileName_ECG.log. Timing information is stored in logFileName_Info.log an external trigger events in logFileName_EXT.log.
