Upward compatibility

Prism 7  can open all files created by earlier versions of Prism, including .PZM files created by Prism versions 1 to 3.

Downward compatibility

We have done extensive testing to make sure that Prism 6 can open Prism 7 files. When Prism 6 lacks a Prism 7 feature, the result is sensible.

We have not tested opening Prism 7 files in Prism 5 and earlier. It will probably work ok for many files, but this is not something we have tested.  

The location of analysis results may change between versions

When you open a Prism file on a version different than the version it was created on, results also may appear on different rows of the results tables. This means that results tables embedded on graphs may no longer show the results you care about, and scripts may export the wrong values. You may have to do a bit of clean up to make the files work as intended.

File compatibility between Windows and Mac Prism files

The Windows and Mac versions of Prism use the same file format, and you can go back and forth without any special conversion.

Compatibility of Prism objects saved within other documents

On Windows (but not Mac), when you paste a Prism graph or layout within Word or PowerPoint (or some other programs), you can paste just a picture, paste a link, or embed a Prism object. If you paste a link or embed an object, you can then double click on that image to edit within Prism. This works only if the correct version of Prism (or the GraphPad Prism Viewer) is installed or a newer one is installed on your computer.
