Dear Gustavo,
There are two ways to go about saving an analysis:
1). If you set up the analysis using the GUI (i.e. based on the graphical data panel), then you can save the entire thing as suggested on page 20 of the tutorial: switch to the data panel you want to save, go to File->Save menu, and make sure to include the data in the file (there will be an pull-down menu in the file save dialog for that). You can later reopen the saved analysis by choosing File->Open Batch File and then selecting the previously saved analysis. Note, that you may have to reopen some of the windows (parameter table, trees etc) after you reload the analysis, because by default only the datapanel (with partitions) will be displayed.
2). If you want to export any kind of likelihood function (this is presently limited to functions based on a single alignment, albeit multiple partitions are also allowed), you can drop this file:
Multimedia File Viewing and Clickable Links are available for Registered Members only!! You need to
into the UserAddIns directory of your HyPhy distribution, and then you will have access to the 'ExportLikelihoodFunction' option when you click on the button with two gears (top most on the bottom right) in the console window (it's tool tip should say User Actions).
Cheers,
Sergei
