[BioPython] How to automate "save column scores to file" in clustalx?

[Hyunchul Kim]

Hi, all

I need 'quality scores' of clustal.
ClustalW provides only 4 degrees by simbols (*, :, ., ' ') and biopython
supports it.
ClustalX provides quality scores and it can be saved via menu 'Quality' ->
'save column scores to file'.
However, I couldn't figure out how to do it automatically such as command
line or biopython scripting.

More specifically,
ClustalW can produce the 'quality scores'?  or
ClustalX can produce output containing 'quality scores' by command line? or
Any other suggestions?

Thanks
