TPC5 File Format
TransAS Version 3.x and newer is saving trace date, spectral data and TabPages in HDF5 file format. Depending on the data type the file extantion is *.tpc5, *.tps5 or *.tpd. The HDF5 file format was developed at the University of Illinois. The HDF5 specifications and the libraries source codes are open.

An HDF5 file is composed of groups and datasets to store and organize signal traces. Recording information such as the recording time is saved as attributes which then can be added to the groups.
To ensure an accelerated display view even with large recordings in TransAS, additional signal traces with reduced data sets are included in the file.
Since TransAS version 3.1.5.46 the following settings can be included; the hardware settings, layout configuration, formulas and the used auto sequence.
HDF5 provides also to possibility to compress the data with the gzip compression algorithm. This option can be selected in TransAS.
Third-Part Programs
HDFView
The programm HDFView allows to open file which were generated by TransAS:

MatLab
The software MatLab is also capable to import directly HDF5 files. As TransAS is storing the data in a binary form a recalculation must be made for getting voltage or physical scaled data. See the import example in the download section.
