Dear Rekha,
Just thought it might be worth mentioning that the c2x software
(https://www.c2x.org.uk/) provides a straightforward interface to spglib
and can read/write both CIF and Quantum espresso input files. One would
invoke it with the --primitive operation to do what you require.
Best,
Michael (not the same Michael that wrote c2x)

Good, you have already used the dev branch. Then you can check more details through
ipython (exceute "ipython" in your terminal)
In the python IDE,
In [1]: import mcu
In [2]: mcu
Out[2]: <module 'mcu' from '/Users/fang/mcu/mcu/__init__.py'>
In [3]: mcu.CELL
Out[3]: mcu.cell.main.CELL
You can examine that the loaded MCU is indeed the one you used or not.

Hello, Rekha
It seemed the latest version of 'dev' branch of MCU wasn't properly loaded in your case. Can you execute the "git log" in the cloned MCU? That can help us to know which branch you are using.

Sir,
I am running it on Ubuntu18.04
steps I followed are:
git clone -b dev https://github.com/hungpham2017/mcu.git
cd mcu
sudo python3.7 setup.py install
updated path in ~/.bashrc as
export PYTHONPATH=/home/rekha/mcu:$PYTHONPATH
source ~/.bashrc
cd ~/case
my mcu.py is
#!/usr/bin/env python
import mcu
work = mcu.CELL(cif='conventional.cif')
prim_cell = work.to_prim_cell()
work.write_cif(prim_cell, filename='primitive')
the ~/case directory is having a conventional.cif file.
Now I run
python3.7 mcu.py
I am getting the same error what i get at the start:
Traceback (most recent call last):
File "mcu.py", line 2, in <module>
import mcu
File "/home/rekha/case/mcu.py", line 3, in <module>
work = mcu.CELL(cif='conventional.cif')
AttributeError: module 'mcu' has no attribute 'CELL'

It looks me like there is some problem with the Python interpreter in your environment, not the code itself.
You can try to add this following line at the beginning of your python script and rerun it:
#!/usr/bin/env python
I found a similar problem here [1]:
by the way, are you running it on a Window?

Hell Rekha,
I guess you downloaded the master branch, I haven't had time to document the codes yet with many new functions.
Hence, the latest code remains in the dev branch, please:
git clone -b dev https://github.com/hungpham2017/mcu.git let me know if you have any other questions. Hung

Dear Sir,
I have cloned it and then added the path to ~/.bashrc.
But my import mcu is not working.
My python path is:
export PYTHONPATH=/home/rekha/mcu:$PYTHONPATH
I have created a file "mcu.py" in which I kept import mcu
work = mcu.CELL(cif='conventional.cif')
prim_cell = work.to_prim_cell()
work.write_cif(prim_cell, filename='primitive')
and then invoked
python mcu.py
this gives me error

I am having my conventional.cif in "/home/rekha/case/" directory.
What should I do now?

Sorry, there was a typo in the example script, it should be this:
import mcu
work = mcu.CELL(cif='conventional.cif')
prim_cell = work.to_prim_cell()
work.write_cif(prim_cell, filename='primitive')

Hello Rekha,
Spglib library [2] is doing what you are looking for. Spglib has a python interface and can be easily installed via Pip or conda..
But you need to make a cell tuple (from CIF) which contains the lattice information, this requires some minimal Python programming.
My MCU [3] project supports CIF file as well as the QE output files and it has cell analysis functions using spglib. Within a few lines of code, you can get what you want in the desired format. For example, in a Python interpreter or script:
import mcu
work = mcu.CELL(cif='conventional.cif')
primitive = work.to_prim_cell()
work.write_cif(prim_cell, filename='primitive')
If you are interested in this, I can assist further.

My materials are very new and not available in any database.

Hello Rekha
You can check out "Material Project".
It's a database where researchers share their findings and results of several different types of materials and of different applications.
Every compound is available in primitive, conventional, computed and symmetric unit cell, etc.
Hope you find this useful.

Dear Expert Users,
It is possible that this question has been answered many times before but I could not find it on the forum.
I have few complex structures and it is not possible to handle on my system in the conventional form.
Can you please advise any tool that can help me to convert a conventional cell cif file to a primitive cell file?
I have tried with VEST (niggli cell reduction) but it does not work for me.
Thank you very much.
Rekha
