Dear @mgracia9 ,
could you please provide us with:
Many thanks
I tested with the recent master branch and it works for me. I cannot reproduce the error. Note that the lattice is already parsed in the setup namelist, so you have to put the sequence definition before the set-up to make it work.
Best Sven
Input deck is:
&sequence_const label = test c0 = 0.84853 &end
&setup rootname=Example1 lattice=Example1.lat beamline=FEL lambda0=1e-10 gamma0=11357.82 delz=0.045000 shotnoise=0 nbins = 8 &end ....
and the lattice file:
D1: DRIFT = { l = 0.44}; D2: DRIFT = { l = 0.24}; QF: QUADRUPOLE = { l = 0.080000, k1= 2.000000 }; QD: QUADRUPOLE = { l = 0.080000, k1= -2.000000 }; UND: UNDULATOR = { lambdau=0.015000, nwig=266, aw= @test, helical= True}; COR: CORRECTOR = { l = 0.24, cx = 1e-6}; FODO: LINE={UND,D1,QF,D2,UND,D1,QD,COR};
FEL: LINE={6*FODO};
and I am getting the desired value for aw.

Lattice:
D1: DRIFT = { l = 0.44}; D2: DRIFT = { l = 0.24}; QF: QUADRUPOLE = { l = 0.080000, k1= 2.000000 }; QD: QUADRUPOLE = { l = 0.080000, k1= -2.000000 };

FODO: LINE={UND,D1,QF,D2,UND,D1,QD,D2};
ARAMIS: LINE={6*FODO};
This I can reproduce. I will have a look into it

I fixed the error and released a new master branch. I would like to mention that the feature of using the lattice namelist to alter values of the lattice will become obsolete in the future since it is much easier to include the reference to the sequence directly in the lattice file as shown in my first message in this thread.
I would like to report an issue with the current version of Genesis. I tried to use &sequence_const. I set the label name to label=test and &lattice value = @test, when running the code .. i get the error:
Unknown Sequence reference in &lattice: test.
I tried to run the Aramis.in as well from the benchmark/Benchmark4-UndErrors folder and I get the same error.
In an older version of the code, both the Benchmark4-UndErrors and my input file works.
(For reference, the older version of genesis was compiled and ran in a ubuntu-22.04 machine, the newer one that it is failing in MacOs-sonoma 14.1).
