Returns for a cell array of cell arrays of trees intree,
a cell array of cell arrays of topological genes genes
(for each tree one).
The two-depth of the input/output arrays allows the comparison
between different groups of neuronal trees.
The topological gene
(introduction section “topological gene”)
returns for a sorted labelling of a tree
(see “sort_tree”)
for all branches (delimited by topological points)
the metric length and the ending point type (termination or branch).
Examples:
>> gene = gene_tree({{sample2_tree}}); gene{1}'
[21 29 21 8 10 17 9 11 9; → branch length values in µm
__2 _2 _0 0 _2 _2 0 _0 0] → branch ending topological point
descriptor (0: terminal, 2: branch)
>> dLPTCs = load_tree ('dLPTCs.mtr'); → load groups
of tangential cell reconstructions
>> genes = gene_tree (dLPTCs, '-s');
