Section 8 - Other Features

This section discusses, briefly, a few newly added or under development features in scanSTAT

Noise Sysnthesis

 
In many cases, the effects of analysis processes such as smoothing and global normalization are somewhat diffiulct to anticipate. For this reason, we have decided to include a Noise Simulation feature. At this release it is not fully enabled, though the Tools folder, in the Sample Data, contains a command line version (undocumented, at this time, but you can safely try it). With the niose simulation, you will be able to modulate the pixel intensities at well defined locations, according to your choice of time course (specified with a Paradigm File). You can also add rayleigh-distributed noise to the image. Using the synthesized images, you can assess the effects of various processing options on the detection of fMRI signals where "ground truth" is well-specified.
