Hello, everybody!

I have been confused about some problems recently! Firstly, I can not be sure that  some kinds of map including p-value map, t-map and z-map  whether are  created or not when processing the fMRI data using FSL! Secondly, if they are created in the processing of fMRI data, what kind of files is created respectively! Finally, what are the differences among the three kinds of map and what key techniques are used in the these maps?  

Best wishes! I'm desperate for your answers!
