==Handling the register block in RAW16 files==
Hello. And Bye.
 
The DNG converter expects the register block to be present so if it has not been saved with the image in camera:
 
To append an empty metadata block (sensor registers):
(cat old.raw16; dd if=/dev/zero bs=256 count=1) > new.raw16
 
To append an existing register block dumped into a file:
cat old.raw16 some.reg > new.raw16
