<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have some files which have coordinates in this
format:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT size=2>
<P> 302.66 305.11</P>
<P> 305.76 305.63</P>
<P> 307.57 307.18 </P>
<P> 310.42 310.54</P>
<P> 311.71 313.13</P>
<P><FONT face=Arial>The first in each line is the x coordinate and the second is
the y coordinate.</FONT></P>
<P><FONT face=Arial>Each of this set of coordinates form a polygon (first and
last point in the file are the same). And each set represents a lesion in the
brain (from MRI images). What i want to do is create the brain volume (which i
already did) and together the lesions from these coordinates. Each textfile
refers to a specific slice of MRI image. For example if i have these images

<P><FONT face=Arial>IM_00104</FONT></P>
<P><FONT face=Arial>IM_00105</FONT></P>
<P><FONT face=Arial>IM_00106</FONT></P>
<P><FONT face=Arial>IM_00107</FONT></P>
<P><FONT face=Arial>IM_00108</FONT></P>
<P><FONT face=Arial>IM_00109</FONT></P>
<P><FONT face=Arial>and for <FONT face=Arial>IM_00105 i have 3 textfiles,
one for each lesion in that slice. Same happens for <FONT face=Arial>IM_00106
but with one lesion. How do i create a volume for polygons in consecutive images
or just create the polygons in each image (for example if i have a lesion in
IM_00108 but not a lesion in images IM_00107 and
IM_00109)?</FONT></FONT></FONT></P>
