Dear Louis, Advice on IMP In the IMP series there is a bug for CVA, Probably your text file including the codes needed for CVA is not in the file of IMPseries, probably it is somewhere in the dekstop or in an other file. In this situation PCAgen will work because it can find the code file inside the computer, but not CVAgen. In the question 2 I have no idea at the moment but I can try to do something if you send me the data. Murat Aytekin
