hi folks
I've had a look at Quentin's images, and have found out that some of
the information that we are using in Mosflm to determine the pixel
size and the beam centre is missing.
For the record, if anyone else wants to process NOIR images with
Mosflm and notices this problem, you should (for the present) tell
Mosflm that the pixel size is 0.07767mm (same in both X & Y) and also
convert the beam centre from the image header from pixels to mm -
while noting that the beam co-ordinates in the header are swapped in
X & Y compared to the Mosflm definition.
Sorry for any inconvenience - we'll get this fixed for the next release!

Dear All,
I used MOSFLM 7.0.4 to open some images originally collected on a
NOIR-1 detector at the HHMI beamline at ALS.
Problem #1: the resolution is not displayed accurately, even tough
the reader seems to be read correctly (instead of being 1.28 in the
attached example, it should be around 8 angstroems).
Problem #2: autoindexing fails, which I now think may be related to
problem #1.
Thanks if you have any input!
