Dear Xavier, I read your email from yesterday, but I thought that his struct file was correct, because I got the same struct file from this cif file: http://rruff.geo.arizona.edu/AMS/download.php?id=13353.cif&down=cif But you are right; if I visualize it, I can see that it is not beta-Sn. Bes

Dear Dr. Tran, You have to remove the "s" from "I41/amds" & then you will get the struct. However, the struct file is always giving 4 equivalent atoms/unit cell. with regards, On Thu, 4 Jun 2020 at 12:40, Tran, Fabien wrote: > Dear Xavier, > > I read your email from yeste

​Dear Xavier, Your cif file can be converted to struct, but only if I remove ​"s" as suggested by Shamik. I tried with cif2struct from old and new versions of cWIEN2k. But, I still get the wrong structure at the end of init_lapw (4 equivalent atoms). If I understood correctly, you did not have

With your modified cif file, I obtain at the end of init_lapw a struct file which has two atoms per cell. Since there is no atoms at the corners, it is visually not 100% clear that it is the correct beta-Sn, but I guess it is (?). I am wondering where the problem with original cif file comes fro

As far as I know, cif2struct supports only the official names of the 230 space groups as listed eg. at the Bilbao cryst. server, but not the (older ??) _space_group_name_H-M_altconvention. For SG # 141 only I41/amd is supported. Only for low symmetry SGs with different setting, more than
