Dear Prof. Gavin, Thanks a lot for your help. It is working now. However, I have another query. After x optimize with the struct file a message comes as: SPACE GROUP CONTAINS INVERSION * alpha(3) .gt. 91.0; reset to 90.1. *However, the struct file remains the same after

I took your attached Nb2Se3_all_min_initial.struct at [1], kept the structure the same but swapped the lattice angles (beta<->gamma), lattice constants (b<->c), and atomic positions (y<->z) in StructGen of w2web and generated the new symmetry operations for it with "x symmetry" which gave the

Dear Prof. Laurence Marks Sir, I have changed the atomic coordinates & reduced the symmetry to 1_P with the help of the Bilbao crystallographic server. The calculation is still running & 3 structures are already generated without showing any error.

Dear Prof. Gavin, If I change a to b, b to c & c to a to make alpha to beta, beta to gamma & gamma to alpha the produced structure shows unphysical RMTs for all the atoms.: 1 for Nb & 0.51 for Se. What to do? with regards, On Mon, 24 Aug 2020 at 16:07, Gavin Abo wrote:
