[ccp4bb] XDS orientation matrix inconsistent with Mosflm, DENZO

2014-12-28 Thread Igor Petrik
I am working on a small project which requires me to obtain the proper orientation of a crystal lattice with respect to the gonistat and source. I have until now successfully used the matrices from Mosflm and DENZO, which are consistent with each other and define the orientation of the reciprocal l

(I think) these matrices are roughly 180 degrees apart, so they may just correspond to different signs of the axes Phil On 28 Dec 2014, at 21:37, Igor Petrik wrote: > I am working on a small project which requires me to obtain the proper > orientation of a crystal lattice with respect to the g

Takanori and Pierre, Thank you for your quick responses. If you read my post you will see that I used the xds2mos.py script to convert the xds orientation to Mosflm format, but this gives me a result that is inconsistent with the matrix calculated directly by moslfm or DENZO. For orthorombic space

Yes, unfortunately an "orientation matrix" is completely useless without a frame of reference. All it does is tell you where the cell axes lie relative to "X", "Y" and "Z", but "X" may be the x-ray beam, or sometimes that is "Z" and "X" is the spindle axis. Different people have different and
