Dear all, I have the last vesion of chimera 1.4 (27371) under a linux machine. I want to use the measure function. I have two models. The difference between this 2 models is a 5 degree rotation around the x axis.
matrix rotation #1 #0

I think the command does not work in this version (if I misunderstood the command please tell me as well). It always give me the same answer for any different models I did try. Since I have to ask my admin each time I want to install something, could you just tell me in which version of chimera this command will work. Many many thanks. best Julien -- European Molecular Biology Laboratory Structural and Computational Biology Unit Meyerhofstraße 1 D-69117 Heidelberg Max-Planck-Institute for Biophysical Chemistry NMR based Structural Biology Am Fassberg 11 D-37077 Göttingen
Dear Julien, I believe the command is working in your version. It does not compare the two structures, it only reports how one file has been transformed relative to the other in Chimera. If the coordinates in the two file are already rotated relative to each other, Chimera would not detect that. It would report a rotation only if you had moved one model relative to the other in Chimera. If the untransformed coordinates of the two structures are already rotated relative to each other, to find out the rotation in Chimera you could superimpose them, and THEN use measure to report what relative transformation had been employed in the superposition. I hope this makes sense, Elaine ----- Elaine C.
