Hello Sajid,
The crosshairs are chip boundaries on a multi-CCD detector. No need to mask
them.
Your lattice appears to be twinned, on cursory inspection. Also you have bad
cryo - I bet if you improve your cryo, the resolution of observable
diffraction increases by at least 0.3A.
Good luck,
Artem

Subject: [ccp4bb] Maks file in HKL2000
Dear All
I have trouble processing my images on HKL2000. Please
refer the attached snapshot of my image.
I dont understand how the cross (hair) lines came into
my images.
Ignoring the lines and continuation of processing
results in high chi square value.
The question is ...
Can I make a mske file to mask all those regions and
do processing. In HKL2000, I believe that I can make
mask file for beam stop and one more region apart from
beam stop. But I do not know whether I can make mask
for all four lines and do processing. If so please let
me know.
Thank you
Sajid
