The psl output shows the native blat output with exons (aligning 
regions) chained together with introns (gaps) between them.

When you choose blast output, each exon is reported by itself
with no chaining.

As far as why the scores look different, that's just due
to the way the psl and blast formats are defined differently.

I have two output files from blat. One is psl and other is blast format.

When I compared the results it looks different, there are no matches 
above 124 and below 34 in psl.

Blast format output result has higher of 272 and low of 12. Why is it so 
different?

I have not changed any parameter, everything is in default. I appreciate 
help from you.
