Updated SPM Command Line, Including Beta Series Option

I've updated the code of the previously discussed previous script in the previous post, previously, including the addition of more help text to explain certain options and termination of the script if the timing file is not found.

However, the biggest change is a block of code to convert the timings files so that each trial is now a regressor, before entering them into the GLM. With so many regressors, the GLM will look a little funky; possibly something like this:

Note that, since there are so many regressors and so many scans, not all of them are going to be labeled individually; but it should look as though there is only one estimation per column, or blip of white underneath each regressor. Also due to space constraints the parameter estimability may not be completely visible, but when each trial is being estimated individually, you should still get a beta for each trial. Check the output directory to make sure that you have the number of betas you think you should have: one for each trial, plus the amount of session constants (usually equal to the number of runs for the subject).

The updated script can be found here; as always, send me any comments if you encounter any serious issues or bugs. I recommend using it as a replacement for the previously discussed previous script, since it can either estimate each trial individually or average them together, depending on whether you set the DO_BETASERIES flag to 1 or 0.

All of this is explained clearly in the following video:
