Hi,
I was referring to P42(1)2, which is the CCP4 symmetry number 90.
I am working on 2D membrane protein crystals and cryo-electron microscopy
images of these, where I initially deal with two-dimensional projection images,
which are eventually merged into a 3D dataset. Therefore my sloppy for
Yes I was also confused by the fact that P4212 is obviously a space
group (upper case 'P') whereas p4 and p1 are plane groups (lower case
'p'), as stated. Not sure what 'p2121' is though, I assumed it was
somehow related to the p2gg plane group (no 8). Also there's no plane
group 'p6212', but the
I am confused by the discussion on this message. Although it says
plane group I assume it really is a normal 3D tetragonal space
group, P42(1)2
So Eleanor's suggestion should work and sftools expand command will
do the job as well.

On 2nd thoughts I guess you could do it in a space group that's a
supergroup of the plane group say with all l and all z = 0. Then you
could use symm x,y,z and it would just ignore the z components (I
think?).

Apologies - I didn't notice the plane group..
Although I think if the sym ops are correctly listed in the P4121 file they
will just be applied as given..

I didn't realise the CCP4 suite could handle the plane groups: where
are they listed (they're not in symop.lib or syminfo.lib)? Or are
they doing some clever projections of the space groups?

Cad will do this correctly
Reflection utilitied - merge mtz ( rather confusing job title - sorry..)
mtz in - the P4121.mtz data
Output - P41212-ext.mtz
Defne mtz output
Select define limit for refl;action by Laue code select P1
then you will get a list of all P1 reflections with phases correctly
