Configure GBTs from file
Summary
At the moment the configuration of the GBT is done with three configuration files (one for each GBT) stored on the DAQ machines and applied in the configuration for all the optohybrids. This is not ideal because ad hoc parameters should be used for each GBT, e.g. the proper phases for the VFAT communication that are the result of the corresponding scan. The results of the GBT phase scan can be stored in txt files on the AMC, with the other parameters needed for the GBT configuration, and this files should be used for the configuration of the detector. In this way, for every optohybrid the optimal parameters are used for the configuration.
