[modeller_usage] specify sequence ranges for salign/align2d

Hello-

WIth reference to Tutorial 2 (Advanced Modeling):

http://salilab.org/modeller/tutorial/advanced.html

Is it possible to:

(1) specify the sequence number ranges for the templates to be used in the structural alignment within 'salign.py'?

or

(2) specify the sequence number ranges for the template or target to be used in the sequence alignment within the script 'align2d_mult.py'?

Thanks, Doug
