Dear Twister Helpers Community,

I'm a novice in 2D materials, so please forgive me for my obvious question. 

I tried running get_ang.py many times but couldn't find a solution. I guess my get_ang.inp is wrong because I tried the attached examples, and all worked fine. 

Can anyone please help me explain how to extract a1, a2, a3, b1, b2, b3, celldm_a, celldm_b and range_nm, I observe that a's and b's are the same in the example provided. and also how to prepare basis_pos_crys, and basis_pos_crys_layer2. i know my questions are too elementary but i want to be sure my understanding is right or not so please anyone can help. See attached my POSCAR 

Thank you very much,
Sani

Hi Sani,

Ok; Please go through the paper: https://www.sciencedirect.com/science/article/abs/pii/S0010465521002964 and see if you understand what different options mean.

Please look at one of the examples and get a sense of what each line means. It should be fairly straightforward to extract a_*, b_*, and the rest from the POSCAR file.

Best wishes,
Indrajit
