Thanks bambam, but that's not what I'm after.

Yes that will pull out those with 1 match, but what I'm after is those that have only have one alignment 'section' (i.e. high-scoring segment pair). ...

how to identify blast hits with only 1 HSP (not limit the number of HSP)

Hi,

Is there a way to identify blast hits where there was only one HSP to the database?

i.e. I don't want to limit the number of HSP's displayed, but I want to identify all queries which only...

yes, it cannot find your R installation. Did you install it?
If so, try putting it in your PATH.
e.g.


export PATH=/path/to/R:$PATH


where /path/to/R is where you installed R.

Hi,

For example, it means you count the number of small RNA that mapped to pos 0-250, then 25-275, then 50-300 and so on, and you plot the total number of mapped smallRNA in these 250nt bins.
