Dear All, I pose the question of my last post in another way:
In a DFT+U scheme, I do a vc-relax calculation with an input in which I had set the values for starting_ns_eigenvalue(). In a certain case, the last scf on top of BFGS optimization gives reasonable results. Sometime ago Dr Iurii Timrov pointed out that the last scf uses the self-consistent occupation matrices resulted from last step of BFGS optimization. Now I would like to repeat the last scf manually, what the code automatically executes. To this end, I use ibrav=0, and insert the CELL_PARAMETERS as well as the ATOMIC_POSITIONS form the "final coordinates" in vc-relax. In addition, for the "occupation" I specify occupations='from_input' as stated in the DOC. Unfortunately, I get SEGMENTATION FAULT error. Could anybody please help to manage this issue?

In a DFT+U calculation, when I specify the values for "starting_ns_eigenvelue(m,ispin,itype)" in a certain order, then in the scf cycle, after iteration #1, the WARNING !!! appears that warns about modification according to specified starting_ns_eigenvalue(). But the order of the modified eigenvalues are not the same as the ones specified in the input. Their magnetic quantum numbers "m" are changed. Is there any bug with this issue? Any comments is highly appreciated.
