So if I load the original volume in another visualization tool (e.g. fslview), these coordinates should be right on the border of white/gray matter. Is that correct? I already checked couple of them but wanted to be sure this is the case. Also, if freeview doesn’t get the header information from ascii files, what header info (probably a default one) it uses to plot them? Is there any way we can give those header information separately to freeview?

It's for ease of conversion and such. cheers Bruce On Mon, 2 Nov 2015, Razlighi, Qolamreza R. wrote: Hi Guys, Why converting a surface to .asc format changes its spatial orientation? Specifically, I have converted lh.while to lh.white.asc (using: mris_convert lh.white lh.white.asc) and plot both of them using freeview but they are not corresponding. In fact, lh.white corresponds to the volume image (e.g orig.mgz) but the lh.white.asc doesn't. See the attached screenshot. The red curve is the lh.white.asc. Any explanation would be greatly appreciated.
