Your colleagues may also want to use the Prism 4 demo, which is fully featured and works for 30 days. The viewer is free, does not expire, and lets anyone open Prism files, view all the contents (including analysis choices), and print selected pages. For the same reason, it was not possible for us to program Prism 4 to save files in Prism 3 format.Even if your colleagues don't own Prism 4, they can view and print Prism 4 files using a free Prism viewer. There simply is no way to allow Prism 4 to include all these new features (the list is much longer) and also allow Prism 3 to open Prism 4 files. Prism 4 also offers new analyses (ROC curves, Bland-Altman Plots), major new options in curve fitting (global curve fits, new kinds of comparisons) and can make new kinds of graphs. Why a new format? Because Prism 4 allows for more rows, more columns, more subcolumns, and more sheets. If you pasted a WMF or EMF image (from another program) onto a Prism graph or layout using Prism. Issues With older versions, there is one problem. However prior versions of Prism cannot open Prism 4 files, since Prism 4 saves files in a new format. The Windows and Mac versions of Prism use the same file format, and you can go back and forth between Prism 8 Win and Mac without any special conversion. Prism 4 can open files created by all prior versions of Prism (the ability to open Prism 1 files was added in release 4.02).
