Hi All,

I am trying to write a TCL procedure to calculate the interaction potential
between two proteins and I am stuck at the following point.
Let's say:

set HB {-0.022000 1.320000}
set typea [$sel get type]
set ea [lindex ${$typea} 0]
return $ea #Returns me "$HB" and i cannot get 0th item of HB

If someone can assist me at this point I would be grateful.
Before I send this mail, I have searched internet for a TCL discussion list,
but could not find an appropriate one. Do you have one to recommend?

Thanks in advance,
