Hi,
How do I know the version of s2ibis2 is correct or not? From the Syed's mail, it mention about the log file show the wrong version message, is any one how do I tell it? Does it suppose to be "s2ibi2 v1.1 --North Carolina State University"? or "s2ibi2_fix v1.1 --North Carolina State University"?
Best Regards,

Wil,
Are you translating multiple buffers at the same time ? Try running the
s2ibis2 only on an Input model or only on an Output model. There is an
issue of creating too many .spi and .out files..
Next, you should be using s2ibis2_fix version. Your data shows you are
using an older version..
