I didnt realize the following: You read in images from the two wedges collected with the same crystal orientation.
mydata_1_###.img mydata_101_###.img Now when you index ,if you say use images from both "datasets" mydata_1_###.img use image 1,90 mydata_101_###.img use image 30 , 120 The matrix for the second wedge (mydata_101_###.img) is still marked unknown? Isnt this different from the behaviour in the X- mosflm . SHould the matrixes be the same since the orientation was calculated using images from both. Now , If I did not force the second wedge to have the same matrix , using the save to file and read from file method you just described , does the new imosflm use the last calculated matrix from the running session or calculate a new matrix ?..I guess I have to check some of the data I processed with my erroneous assumption to make sure that the matrixes for the two wedges are the same . Thanks for clarifying this.. hari On Mon, Aug 17, 2009 at 9:13 AM, Andrew Leslie<and...@mrc-lmb.cam.ac.uk> wrote: > Dear Tom, > > There is a straightforward way to do what you want.
