This is the older Siemens log file format, which is part of software release *VB*, and can be determined by the file extensions `.resp`, `.ecg`, `.puls`, in combination with an optional `.dcm` DICOM header file for the first acquired volume.

A lot of 7T scanners still use this format.

The Human Connectome Project uses Siemens scanners, and the logfile format that comes with their published data seems to be pre-converted and custom (even though the documentation desribes the VB format). We have implemented and own reader for that and written a little tutorial for dataset **178748** here:

|
|
|
|
https://github.com/translationalneuromodeling/tapas/issues/6#issuecomment-361001716
|
|
|

You will have to download the dataset from the [HCP](https://db.humanconnectome.org/) yourself, we just provide the matlab batches here.

Siemens - VD/VE Tics
|
|
|
--------------------
|
|
|
|
|
|
This is the most recent logfile format of Siemens, included in Software releases *VD*, *VE* and sometimes referred to as the *Tics* format, because all time stamps in all files refer to the same reference point (start of the day) and count in the same intervals or "*tics*" of 2.5 ms from there.
|
|
|
|
|
|
You will recognize this file format via the extensions `_Info.log` (or `_AcquisitionInfo.log`), `_RESP.log`, `_ECG.log` and `_PULS.log`. Sometimes, it is also written into the DICOM header (`.dcm`) file of your functional data directly. In this case, use [extractCMRRPhysio.m](https://github.com/CMRR-C2P/MB) to convert it to the above separate files before using PhysIO.
|
|
|
|
|
|
Most modern Siemens scanners, such as the Prisma or 7T Tera, use this format.
|
|
|
|
|
|
There are a couple of variants for this format around (e.g., with the WIP Multiband Protocol that is distributed to multiple sites), and PhysIO tries to support all of them. |
