Hi Hari,
This is slightly different, and was indeed a bug in imosflm version
1.0.0. In the new version, released last week (1.0.3) this bug is
fixed, so that if images from multiple sectors are used in indexing,
the same matrix is defined for all those sectors (ie they will not be
marked as Unknown".
Best wishes,
Andrew

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..

Dear Tom,
There is a straightforward way to do what you want.
It is
probably simplest to start by reading in only the images from the
first
segment (0-180). Then do the indexing, cell refinement and
integration in
the usual way.
Then read in the second segment of data. You will notice that in this
second
segment, underneath the Sector name, there is a line starting
"Matrix" and
this will be "Unknown". If you go to the Matrix line of the first
segment,
the matrix will have a name (based on the image template). Double
click on
the name of the matrix. A popup window (Matrix properties) will
appear.
Click on the "save matrix file" icon (a blue disc) and save the
matrix with
an appropriate filename.
Now go to the Matrix line of the second segment, double click (on
Unknown)
as before and this time click on the "Open matrix file" icon (a
folder) and
read in the matrix that you saved from the first sector. You can now
process
the second segment using this matrix.
It would be even nicer if you could "drag and drop" the matrix, this
is on
our "to do" list.
Best wishes,
Andrew

I am an imosflm novice and have a relatively simple question. I have
a 360
deg data set collected in two swathes of 180 deg (one with phi=0 and
omega
going 0-180 and the second with phi = 180 and omega going 0-180).
What is
the easiest way to process the two datasets using a matching
orientation
matrix (or one rotated by 180 deg as it were) so that all the data
can be
merged together. Is there an easy way to do it in imosflm or must one
process the two sets separately and then manipulate later with
pointless
before scalling and merging everything together?
Thanks in advance.
