How do I find the indices of the Self Organizing Map (SOM) training set output

I'm using the SOM toolbox and have created the following:

net = selforgmap([10 10)];

[net,tr] = train(net,inputs);

where 'inputs' is a 5x10000 matrix of 5 parameters with 10000 samples.

using plotsomhits(net,inputs); shows how the 10000 samples are getting clustered.

Question: How do I output where each individual vector is clustered? For example where on the 10x10 grid is vector #1 located?

TIA

Here is an example that should help you:

net = selforgmap([10 10]);
[net,tr] = train(net,inputs); % Classify input data
op_som = vec2ind(net(inputs))';

for each input in inputs, op_som will have a numbering between 1 to n based on which cluster it belongs to.
