The application "algor.exe -s m-n ...." will run the design scenario (-s switch) numbers m through n. If one of the design scenarios between m and n does not exist, then algor.exe stops with an error "one or more of the specified scenarios was invalid". Please run the analyses on scenarios m through n that exist. I do not expect the software to analyze scenarios that do not exist, and it is a lot easier to specify "-s 1-20" than is it to specify "-s 1-5,8,10,13-20" simply because I deleted design scenarios 6, 7, 9, 11, and 12.
