I tried to write the program but due to partial occupancies some residues are repeating which made me so confused.

You couldn't write the program because the data confused you. Did you get confused after writing the first line of your program? Or the second?

I can use Bioperl or some modules.But for my project I need to write a fresh program to parse the information.

How do you judge the "freshness"? Smell, taste, touch?

The program I wrote for another guy last week to do pretty much the same thing wouldn't be any good to you? It would be stale?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
