1. start CM and make new crystal / import .cif / import from library

2. click "measure" and "single-crystal diffraction"

3. should open new program (single crystal) with diffraction. In "live rotation mode" you can rotate either model or diffraction, works bothways...

Hi, you need also the program upgrade "SingleCrystal" for ED simulation. The demo works only for cubic structures.

I already have the upgrade version ,i want to simulate my electron diffraction of Silicon with .cif simulted file , but it's no giving me correct results . some thing is going wrong but i am not able to figure it out

Try new .cif first (like 1st one from here: http://rruff.geo.arizona.edu/AMS/minerals/Silicon), sometimes .cif files can be corrupted...

Or describe more in detail where is the problem. Do you get the structure in main DM window and just cannot open sub-program (SingleCrystal)? I had problem with this once after upgrading, had to reinstall everything...

Upload your cif-file and tell me in what orientation you are interested and I check it; by the way: important for your simulations are the experimental parameter which you are using (specimen thickness, convergent angle, ...)!

This is the two file and i want to simulate along 100 direction, specimen thickness is 100 nm and don't know about convergent ange

Okay, I would say, that you should have twins in your silicon specimen.To simulate these, you need JEMS,  MacTempas or so! At first I would do darkfield imaging to check the diffraction volumes.

Thank you very much prof  Volker, at the moment  i have purchased crystal maker with single crystal , i just want to confirm that i am going right or wrong:

i have attached  simple DC-Si diffraction pattern with .cif file. could you please just check it along 100 dierction

Hi, you have an [1 1 0] incident beam direction!  The (0 0 2) reflex missing in the CrystalMaker simulation, because it creates due to multiple diffraction at the [1 1 1}, compare for instance:

ok thank you very much prof Volker Klemm for your help!
