Guvenc, There are 2 ways that I know of: the first is "save residual" under the File menu. You may have to save the chi(k) and the residuals separately (I have never done this so I'm not sure on the exact procedure) and then overlay the plots in some graphing software similar to Excel. The second is to save the picture showing the fit and the residuals as a metafile and import the image into PowerPoint and modify the image (line size, line colors, etc) using the drawing options (the procedure for this is found here: http://cars9.uchicago.edu/iffwiki/FAQ/HoraeQuestions?highlight=(Horae)|(faq)#head-2536b76fd9a517c8cff6b367d89e9fd03cbf5999 ). -Richard On Tue, Apr 14, 2009 at 5:55 PM, Guvenc Akgul wrote:

Dear Guvenc, if I understood your question correctly, this might be a way to get what you want: when you save the residual as "chi(k)" you probably get a two column file where column 1 is "k" and column 2 is "chi(k)". If you are saving the residual plus data and fits you will have more than two columns in the file, but it shouldn't be hard to identify which is the residual. Open this file in a spreadsheet program (such as Origin, Igor, Excel, etc) and then create a new column, setting its values as [((column"k")^3)*(column"residual chi(k)")]. That should allow you to plot the k-cube-weighted residual as a function of k. Was that your goal? HTH Leandro On Wed, Apr 15, 2009 at 7:55 AM, Guvenc Akgul wrote:
