Dear Abinit users,

Can someone help me with the visualization of eigenvectors at Gamma-point after anaddb? I have installed agate but don’t know how to visualize the modes.

Regards,  
Koyendrila

Dear koyendrila,

With agate, you can open the output of anaddb (.nc file or ddb file) and analyze it:

- type agate in the terminal
- in agate type :o $NameofYourFile to open the file
- then type :m ph for phonon mode
- finally type :add 0 0 0 1 to visualize the first mode at gamma.

If you want to visualize all the modes you can type :add qx qy qz all

There is also a basic help when you type :h in agate.

Best,

Louis
