While reconstructing neuronal trees sudden shifts in the z-axis may occur. This function automatically corrects these effects in a given input tree intree. Any jump in the z-axis > tZ, a threshold difference in z, is subtracted from the entire sub-tree. Before applying this function, check that this is really the adequate way to process these jumps in z.

Example: After introducing a fake jump in the z values of the sub-tree of node #5, „zcorr_tree“ is applied

>> tree = sample2_tree; isub = find (sub_tree (tree, 5));

>> tree.Z(isub) = tree.Z(isub) – 20;

>> zcorr_tree (sample2_tree, 15)
