[Chimera-users] -S option in ksdssp command

Dear All, I'm trying to get an output with protein secondary structure assignment into a text file, using ksdssp command, unfortunately everytime I get error like this: Computing secondary structure assignments for model #0 using ksdssp (Kabsch and Sander Define Secondary Structure of Proteins) with the parameters: energy cutoff <default> minimum helix length <default> minimum strand length <default> -S option not yet available My question is: am I doing something wrong, or -S option is not yet implemented, despite it is described in ksdssp.html help file? thanks, PK
