Hi, I have an SDDS file (attached) in which contains a column of MAL.DP and betaxFinal values (among other things). What I would like to do is calculate (betaxFinal-betaxFinal0)/betaxFinal0 where betaxFinal is the value corresponding to MAL.DP being zero. Just wondering if there is a way to do that ...

Michael,

I was making a mistake on my end. It works now.

Thanks!

Michael,

I do use Windows. When I try to run the alter_elements commands you provided, I get an "Error: no matches for Q2" message. Is this consistent with the error you were expecting for someone running Windows?

Hi, Is there a way to change a parameter for an element not defined in the beamline (optimization_covariable doesn't work)? E.g. cell1 = line(b1, d1, q1, d1, b2) cell2 = line(b1, d1, q2, d1, b2) I want to optimize cell1 using q1 but also want q2 to take on that value as well. Sure, I can just copy a...

Michael, So to implement a third-order transformation I can write the following commands in a script and get the desired result. I know you can call scripts from within Elegant, but when I try to use these command lines, Elegant doesn't run and complains of "get_param_name(): no parameter found in s...

Hi,

It appears that a KQUSE element is not represented in the magnet layout when it is plotted. It would be nice to have it visible.

Hi,

Is there a preferred method for monitoring the energy loss due to CSR through a chicane? Thanks.

It would be nice if EMATRIX could provide third order terms (e.g. U5666). Is there a quick and dirty way that I could implement that at present? Thanks.

Hi,

I have a linac comprised of a number of cavities. I would like to vary the phase at which these are run. Is there a way I can define a single phase variable in the lattice file and change one number rather than many 10s of cavities individually?

Thanks,
chris

Fantastic! For some reason I had been using printout="%s.mpr" rather than SDDS_output. Thanks.
