Since the format conversion utility was removed from the current version of GITSA, users should write their own conversion script to convert their data to the GITSA native format (GTS).
Pierre Sakic, one of the GITSA software users, has recently developed a Python script to convert the
PBO POS format to GTS format. The script requires Numpy and already
tested with Python 2.7.5 under GNU/Linux platform. This script as well as a readme file and some examples are accessible here.
