External Email - Use Caution

Hi,

i want to create a lookup table for the vertex correspondence between the subjects A & B (pial files). e.g verticesA(100) corresponds to verticesB(122)

Of course the number of vertices is different between the subjects, e.g one vertex of A can correspond to several vertices from B.

Currently, I am reading in the pial files of subject A using 'read_surf' and create two label files (lh/rh) containing all vertices. In order to get the corresponding vertices of Subject B, i use "label2label".

label file A: #!ascii label, from subject 142350 0 -7.814680 -88.725967 9.598738 1.000000 1 -8.505306 -88.835274 9.457685 2.000000 2 -9.234029 -89.900490 9.420641 3.000000

resulting label file: #!ascii label , from subject cvs_avg35_inMNI152/Segmentation vox2ras=TkReg 137427 888 -7.179 -84.047 -28.333 1.0000000000 642 -7.533 -84.272 -28.382 2.0000000000 637 -7.717 -84.612 -28.118 3.0000000000

But how can I interpret the result? Can I assume that verticesA(0) corresponds to verticesB(888)? Or verticesA(0) corresponds to verticesB(888)?

Or is there another way to create such a lookup table?

Thank you in advance!
