Hello monks,
I have a file which has the following format:
>name_of_protein
sequence_of_protein
Now, tha thing is that the same protein might appear more than once, say you have:
>protein1
ASFGTHTRHTHRHTHTRHTRHTR
>protein2
ERYRYTRYHTRHTGEFEWWFEEFFFFREFRGRE
>protein3
AWEERERGRGRGREGRGREGRRRRRRRRTTHTHTRHRHTRHTR
>protein2
AASEFEFEFE
>protein4
>REYTRHTRGRVEVCREVR
What I need to do is: Read the file, when you see a protein (e.g protein1), store the length of the sequence(the line below) and then, scan through the rest of the document and, if you find the same protein name, compare the length of the sequence you found previously with the one you found later and store the initial protein name along with the sequence which has the biggest length.
In my example, the hash should store protein2 with the sequence it finds in the first place, because it is bigger.
