[Genome] finding homologe gene

[Keren Avital]

Hello, 

Im trying to find a homologe gene to a pseudogene by using Blat.
But im getting too many results, some of them have very short matches comparing to the sequence length.
How can I tell if a result is good enough to be a homologe gene?

For example, im trying to find:

And Im getting too  much results, some of them have very few matches.

If you have another way to find homologe genes for pseudogene that would help too...

Thanks,
