try to calculating PCC for all the pair-wised genes for the file "data.zip" with c/c++/perl/python/java or other commonly used language, in data file, each row represented a gene, column represented the samples. see PCC defination here: http://en.wikipedia.org/wiki/Pearson_product-moment_correlation_coefficient requirements: 1. results should look like this one: gene1\tgene2\tpcc1\n gene1\tgene3\tpcc1\n ... gene2\tgene3\tpcc1\n gene2\tgene4\tpcc1\n ... 2. define two parameters for programe input, first to be the input, second to be the output file name; 3. the program must be functional, and the results should be correct. bonus: 1. try to mimic the time cost; 2. mutiple-processing/CPU calculation is encouraged; 3. detailed helping messages is encouraged; 4. friendly GUI is encouraged;
