How do I find out which measurements are assigned to which self organizing map neurons in the Neural Net Toolbox selforgmap?

For an example of 150 measurement vectors which have been trained / processed with the selforgmap function of the Neural Net Toolbox (into an 8 x 8 SOM), how do I find out where the original measurement vectors have been assigned to? and what is the indexing of the MATLAB SOM (numbers increasing as one would read the sentences on a page of text (left to right and top to bottom)) or in some other fashion?
