It is possible to simultaneously display 6 different volumes of interest using the SeqROI Tool. Note that you need to decide which VOL you are in before you do anything. For example, it is not valid to have VOL=0, to draw splines, then click on VOL=1, and then print vol to save the splines, as Braintool will write out the splines in VOL 1, not the splines you've drawn in VOL 0.
Removes all of the splines in the given VOL.
This writes out an ascii file containing the volume of the voi, and details of all the control points of all the splines in the given volume. The file you write to is given by the Directory and Filename fields. Note that no extension is needed, Braintool automatically adds .voi# to the filename, where # is 05, according to which VOL is chosen.
This reads in the voi specified by the Directory, Filename and VOL fields, and displays the splines in the sequence and threed Tv's.
