This page is a reference for students working on the final project. These are the questions that we have often received this year and last during the second week of the course.

• How can I streamline my analyses so that I am running multiple subjects sequentially?
  
  1. If you create batches for an analysis step for each subject and save them, you can load them (using File –> Load batch in the Batch Window) all simultaneously. They will appear in the batch window in the order you selected them and if you press the RUN button they will run one after another.
     • To further streamline: If you named them all the same, for example: “batch_slicetime_… .mat”, you can use the Filter function of the File selector and type in: batch_slicetime and then click on the button to the left with Re on it. SPM will then look in all of the subfolders for any files with that name and select them.
  2. You can set up all of the preprocessing steps or multiple statistical analysis steps for a single subject using dependencies, if you know what the output of each of the previous steps are.
  3. The scripting tutorial describes how you can semi-automate the analysis by programming a bit in Matlab. It is advisable to use this step only if you have a bit of experience with programming Matlab, otherwise it might take just as long as doing it manually.

• How do I know if a step of my analysis is still running?
  • The progress bar in the lower left window in SPM usually shows you whether something is running. However, the only way to really know if your analysis step is complete is to go to the Command Window in Matlab (in the main Matlab window) and see if you have two lines of text that say “Done”. It must be twice for the whole batch to be finished, otherwise just one step in your batch is complete.
