Thanks Yitzle and Rob for you quick response. I apprecitiate your help and writing style tips. I just want to give more clarification about the data format in the file. The sample data file looks the following. ( I removed all the DNA specific alpha numeric codes) _begin class (....dna sample 1) _end class _begin class ...(more dna sample 2) _end class ... The problem is that sometimes because of bug in our software, it does not generate '_begin_class' or '_end class 'when processing from multiple dna sources. So, I wanted to let people know that manual intervention is required if we happen to see, a) _begin class does not have corresponding _end class b) likewise if we see 'end class', you should expect to have '_begin class' and not '_end class'. I mean (example of wrong data file) _begin class ... blah ... _end class .... ... _end class << here it is missing _begin class Hope this is clearer.
