Hi Larry thanks for having a look at it,
here are the command that we have tested with:
# oiio command
oiiotool -v -stats -info texture_master.1001.tif -resize '50%' -o
/tmp/resized.tif
# imagemagick command
convert texture_master.1001.tif -resize 50% /tmp/resized.tif
Where the input texture_master.1001.tif have these properties (extracted
with oiiotool -v -stats):
texture_master.1001.tif : 2048 x 2048, 3 channel, uint16 tiff
channel list: R, G, B
oiio:BitsPerSample: 16
Orientation: 1 (normal)
DateTime: "2012:10:25 18:45:43"
tiff:PhotometricInterpretation: 2
tiff:PlanarConfiguration: 1

tiff:RowsPerStrip: 32

Thanks!
