Angel's probably got the best idea. You can do that by using the extended
select command:
select {*.ca} (resno % 2 == 0)
for example. That is, you can do any math you want on any atom property by
including it in parentheses after the selection in braces. But whether or
not you can connect them.... I guess they are in order in the file. Maybe
it's simplest just to do a FOR loop.
