The 'chainInfo' output is very complicated. I would suggest using the
"show chain" command instead, for example like this:
select protein;
var chain_count = script("show chain").lines.size - 1;
print chain_count
The "-1" is in there because the "show chain" output has always an empty
line at the end.
Useful for determining things like this is using the "show" command
instead of the "print" command for looking at variable values:
var x = script("show chain");
show x;
