Modify maker notes of Pentax's pixel shift files

[rechmbrs]

I'm new to exiftool and the gui.

I have a Pentax K 1 and shoot pixel shift resolution DNG files.   Because of the movement between shots, the resultant output is a real mess in areas of movement.   I'd like to be able to change the tag Quality in each of the four files maker notes to RAW from RAW (pixel shift enabled)  using the gui preferably and output a new file with "NOPSR"  included in the filename.   If not the gui,  how do I do it using just the tool?

Thanks in advance for the assistance.

Ps:  my gui found the tool using the directions available.

I can't give GUI specifics, but I think you need to put the Quality tag in the working tags, then enter RAW as its value.

From the command line, it would be:  exiftool -quality=raw FILE

Phil,
Thanks for the quick response.   Worked once I put filename.

Another thanks for your continued effort with exiftool. 

Chimo,
