TRestRawBiPoToSignalProcess Class Reference

Detailed Description

An process to read binary data from BiPo electronics.

The TRestRawBiPoToSignalProcess reads a binary file based on the BiPo acquisition. This acquisition consists of several Matacq boards that register waveforms coming from two different sources managed by the BiPo trigger configuration.

This process reads the header of the input file placing the header information in two different c-structures MatacqBoard and BiPoSettings.

For the moment the input file needs to be read uncompressed. If we got compressed data, we will need to uncompress it before start the processing with restManager, as follows:

gzip -d -c /path/to/binary/data/BiPo3Mod2_run_2600.data.gz > /tmp/BiPo3Mod2_run_2600.data
restManager --c /path/to/rml/BiPoToRawSignal.rml --f /tmp/BiPo3Mod2_run_2600.data
rm /tmp/BiPo3Mod2_run_2600.data

The file BiPoToRawSignal.rml can be found inside the pipeline/external/BiPo.

Additional information might be found at the following PR.

The produced event consists of 4-channels, each channel being divided in two time windows, the first window goes from 1 to 1500 samples, and the second window goes from 1501 to 2460.
