The trace reading library should be able to deal with cross-endianness, but maybe you're hitting something else. This is all I can think of at the moment. Anyone else has an idea? The problem of different channels in different trace directories is definitely a bug. All of the development effort is currently going towards UST 2.0, which will offer much more robust session handling. It'll definitely be worth retrying it with the new version.
