PAKtools - PAK2Mat

About PAK2Mat:

PAK2Mat allows a PAK/MKii user to convert his/her measurement and descriptive data to MATLAB for further processing. The conversion is either performed directly from the measurement data binaries or alternatively from a PAK generated ATFX file. Use Drag & Drop functionality from either PAK, PAKtunes or the Windows Explorer to start the conversion. The PAK2Mat Queue List will be filled and PAK2Mat starts the conversion to MAT file(s) for you. You can see the progress in the command line window. That's all there is to it!

BACKGROUND:
Müller-BBM VAS is a member of the ASAM ODS community. The ASAM organisation aims, among others, at standardizing measurement data. The standardization allows PAK measurement data exchange to other measurement system vendors that are ASAM members as well. Effectively within PAK5.x users have the option to generate a so-called ATFX file. This can either be the header file (header.atfx) only along with the PAK measurement data binaries or a new combination of header file and duplicated measurement binaries like Throughput and Analysis. Either way, PAK2Mat uses the ATFX header information to not only convert the measurement binaries to MATLAB but also add extensive information how the data should be interpreted (linear or logorithmic, units, applied window functions and correction factors, etc.). Furthermore information about the test candidate and conditions are provided along with (optionally) the sensor locations.


RESULTING DATA CONTENT IN MATLAB:

  • Your measured data like throughputs, APS etc. as MATLAB double precision values along with extensive information how the measurement data was generated. It for example contains additional fields to specify the Unit, Scaling, Window functions, Energy correction values, etc.
  • Not only your measurement data but your complete measurement definition is converted. The MATLAB object for example also contains information on the Sampling Rate, Measurement Channel Names, Date and Test Candidate information.
  • Optionally also convert the sensor locations (x,y,z coordinates) to MATLAB with a PAK5.8 installation.


SYSTEM REQUIREMENTS:

  • Windows 7 or 8 either 32 or (best) 64bit
  • Min. 4Gb RAM
  • It is recommended to use an SSD disk as most of the processing involved are read/write operations
