Whenever I attempt to perform ghost analysis in OSLO, the ghost icon on the spot diagram toolbar is deactivated.

Whenever I attempt to use the "ghosts" command from the command line I get the error message "Command is currently disabled." How do I activate the ghost analysis?

 

Synopsis

Ghost analysis is not available or is deactivated

Solution

Close the spreadsheet window. The "ghosts" command significantly alters your current optical system during the operation of the ghosts analysis. Although your optical system is rd to normal before the end of the analysis, there might be some problems. OSLO forces the user to close the spreadsheet (thereby saving the lens system to a temporary buffer) before performing the ghost's command.
