Hi,

I am currently going through some tutorials provided by FSL, specifically the FSLUtils tutorial. I am working through a section that involves fslsplit/fslmerge, and I am confused on something the tutorial states. Here is an image on what the text says:

(I know the image is small, but if you zoom in, it should look okay).

Basically, I am confused on the part that states "(note that the * is expanded by the terminal to fit any characters in all possible filenames present, and so can be used in any commands, not just ls, as we will see below)." I am honestly very confused as to what this is trying to say. Any clarity would be fantastic!

This is something that is standard when using the shell (terminal) in unix (or linux or mac). If you have not come across this type of wildmasking then I strongly recommend that you go through the Unix section of our preparatory materials (see http://fsl.fmrib.ox.ac.uk/fslcourse/ ).

You should also find the introductory lecture helpful and would also benefit from the introductory textbook that we've written, aimed at people new the field and those who are taking the FSL Course: http://www.neuroimagingprimers.org/

All the best,

Mark

Thanks
