AHELP for CIAO 4.15 Sherpa
Save the information about the current session to a text file.
save_all(outfile=None, clobber=False) outfile - str or file-like, optional clobber - bool, optional
This differs to the `save` command in that the output is human readable. Three consequences are:
- numeric values may not be recorded to their full precision
- data sets are not included in the file
- some settings and values may not be recorded.
Write the current Sherpa session to the screen:
Save the session to the file 'fit.sherpa', overwriting it if it already exists:
>>> save_all('fit.sherpa', clobber=True)
Write the contents to a StringIO object:
>>> from io import StringIO >>> store = StringIO() >>> save_all(store)
The parameters for this function are:
|outfile||If given, the output is written to this file, and the `clobber` parameter controls what happens if the file already exists. `outfile` can be a filename string or a file handle (or file-like object, such as StringIO ) to write to. If not set then the standard output is used.|
|clobber||If `outfile` is a filename, then this flag controls whether an existing file can be overwritten ( True ) or if it raises an exception ( False , the default setting).|
This command will create a series of commands that restores the current Sherpa set up. It does not save the set of commands used. Not all Sherpa settings are saved. Items not fully restored include:
- data created by calls to `load_arrays` , or changed from the version on disk - e.g. by calls to `set_counts` .
- any optional keywords to comands such as `load_data` or `load_pha`
- user models may not be restored correctly
- only a subset of Sherpa commands are saved.
