Hello everyone, I found that using the unit cell structure obtained by converting the cif file with abipy for calculating the static SHG coefficient would result in incorrect symmetry. This issue is also mentioned in this link (https://docs.abinit.org/faq/pre_and_post_processing/#can-i-use-a-cif-file-to-specify-the-unit-cell). Therefore, I would like to know how to obtain the standard input structure for Abinit. Are there any corresponding programs or websites? The correct structure is shown below.Thanks！

Hi Jiang,
you can use wxDragon which takes several structural input file like cif, poscar to get an initial input for abinit
cheers!
