Hi - thanks for your email. It's possible that the new syntax for avwmerge
is what's causing the problem. For general conversion of lots of 3D files
into a 4D file, you want:
avwmerge -t <outputfilename> <inputfile1> .....
for example,
avwmerge -t OUT *.hdr
If this doesn't fix the problem, maybe you could put your data on a
web/ftp site and we'll take a look for you.
Thanks, Steve.
