<div dir="ltr">Dear wien2k users<br><div class="gmail_quote"><div dir="ltr"> I have a question regarding opticc with spin orbit coupling (SOC). After convergence with SOC, I was trying to calculate optical spectra with "x opticc -so -up" script but it produce NaN in case.mat_diagup file. There is no problem in opticc when i converge the system without SOC. If anyone get this type of problem before, OR know how to correct this error. kindly share your experience with me. <br>
