Please have a look at this topic:

> If you need the full skull as well, you should threshold what you need to get that first. Then what I do is use the “Editable Intensity Range” checkbox to Erase only those dark threshold values that will give you a nice gap between parts. It can be tedious but by setting that editable range, you can be messy when painting over the area and not worry too much about following the suture closely. Once you think you’ve separated it enough, you can create another segment for the temporal bone and us…

If you have further questions then let us know, describing in more details what you mean by “extract the skull suture” (do you need to just mark the suture lines or split the bone along sutures?) and what you mean by “I used shift to make the sutures more evident” (what did you shift?).
