Hi All,
Could any one help me in printing the hashes of hashes? the data sturcture is something like this. 
$VAR1 = {
          'LB2241-RCC' => {
                            'rs6557634' => {
                                             'plex' => 'W30467',
                                             'gt' => 'T',
                                             'file' => ' file1.csv'
                                           },
                            'rs1032807' => {
                                             'plex' => 'W30569',
                                             'gt' => 'G',
                                             'file' => ' file1.csv'
                                           },

where LB2241-RCC is a sample, which can have around 60 -89 similar rs6557634 (called snp-ids) and each of them in turn have the the three keys, plex, gt, file. I would like to print them in this format: 
W30467,LB2241-RCC,T,T,T,C,CA,GT,T,GA,C,A,G,CT,T,T,CA,AG,TC,G,GA,C,TC,C
+T,AG,AG,C,GT,GA,G,GA,T
W30469,LB2241-RCC,G,T,T,C,CA,GT,T,GA,C,A,G,CT,T,T,CA,AG,TC,G,GA,C,TC,C
+T,AG,AG,C,GT,GA,G,GA,T

In simple words, I have to get all the snps-ids->gt foreach of the sample and their plex. The same sample could be seen with a different snp-ids and a different 'gt'. Any help in how to print them ? Thanks in advance, your help is much appreciated.
