Dear Jan,
that is an annoying thing with Arp/wARP - it sometimes does not
recognise some space groups, esp. the monoclinic ones with eg can be
called C2 or C121 etc.
Run the mtz file again through CAD, use SG 5 or C2. That should work.
.... and it does! Thanks a lot.
Let's hope these annoying obstacles can get removed from the path of -
otherwise really happy - CCP4 users!
Thanks again,
Anita
Bonne chance

Dear all,
I have a nice MAD map produced by Sharp and would like to trace a
chain into it using Arp/wArp. When I input the mtz file via the
CCP4i interface, I get the following message:
"Cannot extract ARP/wARP asymmetric unit limits
The job will fail if run"
Well it DOES fail when run!
My space group is C2 (given as C121 in the mtz file header), the mtz
file is a standard structure factor file generated by CAD (adding
Sharp phases to native data which are at a higher resolutino than
the MAD data) and I just don't see what is going wrong.
I am using CCP4 6.1.2 and Arp 7.0.1, with the CCP4Interface version
2.0.5 running on Mac OSX version 10.5.8.
Any advice will be extremely welcome!
