Hi, John You haven't really provided enough information for us to help you. The sessionInfo() would be useful so that we know what version of R and other packages you are using. A reproducible example would be great, but barring that, more information about your data (the flowSet, and flowFrames) like the output of summary() or print(), helps us to understand what the input data looks like. Calling traceback() after the error is thrown can also help tell you, and us more precisely where the error occured. If I had to make a guess, and that's all I can do given the information you've provided, I'd say look at the parameter names in your flowFrames. Sometimes R will substitute a '.' for the '-' character in parameter names.
