cpymad in win7 about cpymad

[coldfix]

I'm now back into win7 and get rid of scientific linux because it cracked again.

I didn't try scientific linux so far, but I had no problems on other distributions (ubuntu, mint, debian, arch). I think, I'd recommend mint for beginners.

I have succeeded installing cpymad on my thinkpad with 64bits win7. The process is very successful and no problem has been happened.

Great.

First, I can't modify the assignment to command_log. I want to store command history to my desired place.
`madx=Madx(command_log='E:\cython_madx\test\log.madx')

The backslash \ is an escape character inside strings, e.g. '\t' stands for <Tab> and '\\' stands for a literal backslash. The error message ([...] or filename: 'E:\\cython_madx\test\\log.madx', you can see that only the first and last backslash got recognized as path separators. If you don't want to use double '\\' inside your strings, prefix the first quote by an 'r'. E.g.:

madx = Madx(command_log=r'E:\cython_madx\test\log.madx')

Second, I can't find any MadX file in my disk. I remeber, that there exist amount of MadX examples in linux. What happened to this?

Are you talking about the models which were previously distributed inside cpymad or about log files? As for the models: I cut them out, their license is difficult, I don't want to maintain them, I'm not affiliated with CERN ;). And, as they are data files, they do not belong in a code repository.

Third, could you give me a complete example to begin cpymad?

You can ask me any specific question. The example in the README is examplatory for most of what cpymad can be used for.

Did you read python tutorials and MAD-X manual so far? Without knowledge about MAD-X and python, cpymad will not be useful. cpymad is a python-binding of MAD-X, i.e. it makes the MAD-X library accessible from python. If you don't plan to program in python or make use of data-analysis via scipy/numpy/matplotlib, it doesn't really make sense to use cpymad instead of plain MAD-X.

I mean, .madx file can't be found in my disk anyway. For linux, many examples such as .madx file can be found in some folder. I think this is due to installing libmadx in linux but not for windows, right?

Yes, I have read python tutorials and programmed few pieces of codes via function_based program and object- oriented program is the next plan.
I am reading MAD-X manual and have even not used it.
My goal is to call madx via python and Visualise scientific data.

Currently, I want to make a match for optimizing beam spot at a fixed position by adjusting only few magnets.

Hey, I hope you are fine with the solution I gave you and hence closing this for now as I don't see an open question. Reopen if needed.
