Dear John,

I would like to generate two layers of water molecules each one has 9610
TIP3 molecules.
My problem is the maximum limit of segid is 9999, thus I can not
generate the other layer because of having the same segid, and I can
take advantage of having different resid.

This is my trying:

for { set ResID 1 } { $ResID <= 2 } { incr ResID } {
  segment $ResID {
    first NONE
    last NONE
    residue 1 TIP3}
  coord $ResID 1 OH2 {0.0 0.0 0.0}}

for { set ResID 1 } { $ResID <= 2 } { incr ResID } {
  segment $ResID {
    first NONE
    last NONE
    residue 2 TIP3}
  coord $ResID 2 OH2 {0.0 0.0 0.0}}

Would you help me to solve this problem.

Thanks
