Hello!
I looked at the two files provided by Tom and they are both fine. One
file is a little bit unusual in that it places the blockette #1001
before the blockette #1000. However, that is perfectly fine by the
official miniSEED standard.
The reason, why it was not working is that the GIPPtools code contained
two minor bugs that in combination with the unusual miniSEED file
resulted in a miss-location of the required blockette #1000. The
GIPPtool utilities would then try to determine the byte-order flag from
some random location inside the miniSEED record, which ended in the
dubious (and illegal) value of '39'.
I fixed the bugs already but it needs some more testing before the next
official GIPPtools release.
@Lion: Thanks for the "blockette #100" file, I will look at it next week
in more detail.
Have a nice weekend
Christof
