Hi, I've found a bug in join_vectorfiles (folder SRC_trig). To remove it, do the following replacements: 1) file util.f, line 46 read(unit,"(A16,I2)")dummy,mult ==> read(unit,"(A15,I2)")dummy,mult 2) file util.f, line ~ 102 read(unit_struct,"(A16,I2)")dummy,mult ==> read(unit_struct,"(A15,I2)")dummy,mult Bests, Kateryna Foyevtsova
