Hi Eric,
DBAPP seems not to be working. The error I get and the image headers are
shown below. Note that I've tried various FQTOL values (including -1),
and tried multiple inseq / in2seq values from a string of 13 such files on
disk. I've also experimented with outname/outclass/outseq being an
existing file or one that is to be created. Same error message occurs in
any case. The two data files in the example below can be found in:
/home/parallax/BB388/testfiles
Inputs and error message:

I'm happy to run more tests of the task as needed.
