GraphPad Prism is a powerful combination of basic biostatistics, curve fitting and scientific graphing in one comprehensive program. Because it easily organizes, analyzes and graphs repeated experiments; picks appropriate statistical tests; and interprets the results, Prism is ideally suited to data plotting and analysis applications in the life sciences.
GraphPad Prism V 5 is available for both Windows and Macintosh. The two versions are very similar. You can open files created on one platform on the other platform with no special conversion. The program has almost identical interfaces on the two platforms, so you can switch back and forth with virtually no learning curve. The main difference is that the Mac version does not support Object Linking and Embedding (OLE).

Publishing graphs with Prism
We designed Prism to produce quality graphs. There are a variety of options that are available for publishing your graphs.
Copy/Paste. With many applications you can simply Copy your Prism graph and Paste it into another application. With Prism Windows, you’ll be pasting a Prism object that includes all data and results. Double-click on the pasted graph to edit it with Prism.
Export your graphs from Prism in the format that best suits your needs. Choose from:
TIF – High resolution tif files at up to 1200 DPI in CMYK or RGB for publcation
JPEG – web format
WMF – Windows Metafile, Windows only
PICT – Macintosh only
PNG – web format
BMP – bit map format
PCX – bit map format
Post to web sever. With one click you can post your graphs to the web. Simply email the link to your collegues for them to view.
Powerpoint and Word – Prism is designed to work hand-in-hand with Office applications, seamlessly exchanging data and graphics with Word and PowerPoint
Well-organized so you can organize well!
With Prism, you can store all parts of an experiment (several data tables linked to results, graphs, page layouts and notes) in one organized file. You can decide how much information to include in one project file. You can place all your data tables into one file, along with linked results and graphs. Or you can also separate your work into lots of files. Prism lets you choose how to organize your work.
Record experimental details
Because science requires rigorous record keeping, Prism lets you enter unstructured notes and structured data (notebook number, experimenter, lot number, concentration, etc.) onto Info sheets. It’s an ideal way to keep each part of your experiment organized and on target. Each info sheet can be linked to a particular data table or be general for the entire project. You can use info constants as constants in transforms, as constraints in nonlinear regression, and as graph titles and legends.
Save time and help eliminate errors with automatic linking.
If you edit data, Prism automatically recomputes linked analyses and replots linked graphs.
If you exclude a ’bad’ data point, it will remain on the data table (in blue italics) but be omitted from analyses and graphs, which are automatically updated.
If you change analysis choices, the results are recomputed (along with any chained analyses) and linked graphs updated.
If you edit info constants, Prism automatically recomputes linked analyses and recreates graphs where those info constants are used.
If you edit a graph, Prism automatically redraws linked page layouts, even if the graph is included on a layout in a different file.
Summarize your experiments on one page
Prism makes it very easy to create page layouts containing multiple graphs, and provides tools to equalize the graph size and to align axes. These graphs can all come from one project, or each can come from a different project. Either way, everything is fully linked and the page layout will be updated when you edit your data or change the analysis choices. You may add drawings, text, and imported pictures to the layout, as well as data and results tables. This lets you turn a page layout into a complete one-page summary of your experiments for presentations, papers, or your lab notebook.
If you chain analyses (for example, first transform the data, then do nonlinear regression, then do a normality test on the residuals), you can view them in a nested view (data plus results) to clearly document the order of the analyses.
Automatic error bars
Simply enter your replicate values and view the linked graph. Prism automatically creates a graph with error bars. The calculations are entirely automatic, and you may display your error bars as the SD, SEM, 95% CI, mean and range, median and range, or median and quartiles.
Simultaneous analysis of related data sets
Experiments typically compare several experimental conditions. With Prism, one command analyzes and graphs all the related data sets in your data table. You don’t need to repeat commands for each experimental condition.
Instant analysis of data from repeat experiments
You rarely perform an experiment just once; you repeat it to verify the results. Prism lets you analyze and graph data from a repeat experiment instantly. Click once to duplicate the data table, along with linked analyses and graphs. Then enter the new data, and instantly view linked results and graphs. You don’t have to retype commands and don’t need to create complicated batch files or macros. Save even more time by saving your work as a template. Every time you repeat an experiment, simply open the template, enter the data and info constants, and you are done.
