i am using 'nnstart' tool of matlab. i have extracted features of image, stored it in excel sheet, imported that sheet in 'nnstart', I have run 'nctool' of nnstart for clustering data, I got result of it. I can interprete result visually but i want to use these results further in matlab code again. dont know how to do? in which file/variable of matlab these results are stored. This tool has generated two files as result i.e. result.input and result.output. Result.output file shows allocation of each input data to neuron of SOM. now i want to analyze distance value between neurons to find out how many clusters are generated for my data.dont know from where i can fetch these values. Please help
