Hi,

I am interested in performing the same actions several times on several different structures.  For example: open a file, select the histidines, delete them, save and close.  Is IDLE the right tool for that? I opened the python shell (Tools-> General Controls-> IDLE) but could not open files or manipulate them using the shell.  I have no knowledge in python.  What is the best way to write scripts to execute commands repeatedly?  If IDLE is the tool, how can use it to do that? Is there a written source for that? Do I need to master python first?

Many thanks,

Ben
