Dear Keith,

Q1- Yes  you should be using USUBA.

Q2- That error means that USUBA had trouble reading your file.  Most likely there is a read status on your file that needs to be cleared.  Try a CLRSTAT.

Q3- I doubt you can use VLBAPIPE, which is designed for more ordinary observations.  So you should use the set of procedures in VLBAUTIL.  This is a little more cumbersome, but if you are a newbie it would be good for you to see the steps.  Appendix C in the AIPS cookbook gives a good summary.  The basic steps are:
1) VLBATECR (correct ionosphere)
2) VLBAEOPS (correct earth orientation parameters)
3) VLBACALA (amplitude calibration)
4) VLBAPANG (correct paralactic angle -- if you are doing phase referencing)
^^^^^^^^ for above the order doesn't really matter ^^^^^^^^^
5) VLBAPCOR or VLBAMPCL (correct instrumental delay)
6) FRING (fringe fit, there are procedures for this, but  your experiment is complicated enough that I think you should run FRING and CLCAL separately.
7) CLCAL (apply fringe fit to target)
