Hi Joe,
   I assume that you have already 1) defined your FIR function (mkanalysis-sess) and applied it (selxavg3-sess).  I also assume that you have already defined your ROIs (funcroi-config) and applied them (funcroi-sess).  Up to this point, everything is more or less easy. Now, you want to know how to get your time course!  
   You have to use funcroi-table-sess command multiple times!  For FIR analysis, you have to add '-frame X' to your funcroi-table-sess command with X referring to the point in your time course (use funcroi-table-sess --help for more help).  You have to repeat this command for each TR in your time course. For example if you have 10 TR, then you have to repeat it 10 times with '-frame 0' to '-frame 9'.  Please note that, you have to save the results in 10 different files and then read them later somehow (I use matlab for that) and combine them to make your time course.

Let me know if you faced a problem
Good Luck

It is still possible but not quite as easy. You have to create a
contrast for each tap in the FIR, then run funcroi for each tap.
