Hi Jose,
If you just need the different possible segids from water, why not do something like this?
set allwaters [atomselect top "water"]
foreach segid [lsort -unique [$allwaters get segid]] {
puts $segid
#I assume you want to do some work here, maybe making a secondary atomselection, and writing it to a file.
}
I mean, its somewhat abusive to use lsort this way, but it will get you a list of segids with minimal fuss. Would this serve your purpose? I've never actually cared about the number of waters. :)

Hi everyone,
I need to get all the water's segid of a pdb file and write them in different pdb file.
For example:
set water [atomselect top "segid W8"]
$water writepdb waterW8.pdb
In this case, my pdb file contains 8 different segid, so I could do it with a tcl for bucle from 1 to 8, but the problem is what if I have more than 8 segid? How can I count them in the same tcl script??? do I need to get the position of "WX" (X= segid number) of the line (as a string line)?
Hope you can help me!
Regards from Chile!
