Abdurrahim,

You need to use tracking to do this. See the attached files for an example.

Michael,

I tried the 'alphaExpansion' example, and the fitted alphac and alphac2 agree with those from .twi file. In my case(a low alpha lattice), the fitted alphac and alphac2 have large discrepancy with those form .twi file.

In addition, I suppose the orbit length should be based on the closed orbit. It seems that this is not included in 'alphaExpansion' example, and this might be critical for low alpha lattice.

Could you please have a look? Thanks!

Ji
