Hello group, I have a list that I import using list1 = Import["list1.txt", "List"] The text file just has numbers at own lines without any pucntuation marks. importing liek above forms a list. I wanted to then plot using Listplot and look at varuous stats such as variance std dev, mean, cv. etc etc. It works fine for some, except others I'm getting the following errors. Graphics::gptn: Coordinate 6.0562273076786985*^-6 in {174, \ 6.0562273076786985*^-6} is not a floating-point number. Graphics::gptn: Coordinate 2.863757626397791*^-6 in {209, \ 2.863757626397791*^-6} is not a floating-point number. Graphics::gptn: Coordinate 7.261053272010106*^-6 in {351, \ 7.261053272010106*^-6} is not a floating-point number. the lists are generated from evaluating NDSolve interpolating function at a time point. solve routien is repoeated over 5000 random values of a given parameters. Exact same method worked just fine last night. now it's seems to giving errors. what's going on here ? any thoughts will be thoroughly appreciated. sean
