[ccp4bb] the matrix format

[Qixu Cai]

Dear all,

The matrix formats in different program always confuse me.
The matrix format of the "REMARK 290 SMTRY" section of pdb file is:

r11    r12    r13    tx
r21    r22    r23    ty
r31    r32    r33    tz

What's the matrix format accepted by the "transform file" keywords of 
the pdbset program?
is it "r11 r12 r13 r21 r22 r23 r31 r32 r33 tx ty tz"?
And how to covert from the "pdb file format" to the "pdbset format"?

What's the matrix format of "apply NCS operators" in phenix GUI?

Thanks a lot!
