About this tutorial

The main objective of this session is to introduce and to explain the new Python interface for accessing LCLS data from analysis applications. The new software framework is known as the "Interactive psana" or just ipsana. The first idea of implementing such tool was suggested around 1 and a half years ago at the joint PCDS/SRD meeting (look for ipsana). Though its underlying machinery is largely based on the batch version of psana the interface to the data is much simple, more intuitive, and it requires much less code to be written by a user in order to get to "that CSPad image" (EPICS PV, etc.). The new framework won't work for everyone, especially for those users who have either heavily invested into the modular code of the batch frameworks, or who needs the performance of modules written in C++. Still our intent is to demonstrate the power of
