Sorry about the messy code I wrote I know it wasn't actually legit I was just in a hurry and trying to get the basic idea across. Here's a snip from what I'm parsing:

>P30450 | Homo sapiens (Human). | NCBI_TaxID=9606; | 365 | Name=HLA-A; Synonyms=HLAA;M

MAVMAPRTLVLLLSGALALTQTWAGSHSMRYFYTSVSRPGRGEPRFIAVGYVDDT

and the output should look like:
Hydrophobic stretch found in: P30450 | Homo sapiens (Human). | NCBI_TaxID=9606; | 365 | Name=HLA-A; Synonyms=HLAA;
AVVAAVMW
The match was at position: 325
Hydrophobic stretch found in:

The match was at potistion: 170
LLALVAIFF
The match was at potistion: 493
IWICWFAALAA
