Hi I am new to this forum so please forgive me if I make faux pas!
I am parsing a BLAST report using bioperl for some reason one of my hits
which list three hsp is not recognizing them as hsp and during the parsing
they are getting skipped over. I have print to screen output showing two
genes the first is the one I am referring to and the second is one that is
working just for your comparison. I will also paste part of the BLAST report
for those two entries.
I will not paste the code at this time, but will gladly if it is needed. I
am thinking that perhaps I am misunderstanding what an hsp is ... that is
why I am first showing you these two pieces of informations.
Thanks for any help!

I have pasted screen output from my script I use to trouble shoot plus part
of
a BLAT output in Blast format. From the BLAST output you can see I have
three hits on Chr3
it seems to me that this should be three hsp's however these are not
considered hsp for some reason
yet YCL068 is - I pasted part of that report below YCL067
