alex0000 Dear all, I've recently started using TOPAS v4.2 and faced a problem right away. I was trying to learn how to use rigid bodies and restraints for a Rietveld refinement and tried to upload tutorial input files which were supplied along with my version of program (f.e. cime-sdpd-xdd-rigid.inp), but got an error message: "Error loading sstring_in at { process_times } unknown or misplaced keyword". Another similar situation occurred when I'd tried to use Distance_Restrain or Angle_Restrain commands, I'd used the syntax which was offered in the technical reference for v 4.2 though. I finished with errors: "Error loading sstring_in at { sites_distance } unknown or misplaced keyword" as a pop-up message and "sites_distance !m54eb63ef_11d load site_to_restrain { Zr1 O1 10 0 0 0 } prm = !m54eb63ef_11d; : 2.04574" in the log. I barely have an idea what should I change in syntax, especially when I use tutorial inputs which are supposed to be correct, of course. Could anyone explain how to fix these problems or suggest any source or reference that would show how to get rid of them. I'd appreciate any help and thank you in advance.
