[ssml] psi-blast itteration...

[Dan Bolser]

Hello everyone!

Welcome to the list!

I have a question regrding a psi-blast result using scop
sunid 81250 against SPTremble ac Q8WTS6 (using a quite NR
SPTremble as the search space).

I get only a single HSP, but two itterations, and the exact
same HSP has a better E-Value in the second itteration.

Is this a bug or is there some reason why the scoring system
can vary in this way?

I am using the latest version of psiblast ca one month ago.

The important bits of the results are...

       <Iteration_iter-num>1</Iteration_iter-num>
           <Hit_num>1</Hit_num>
               <Hsp_evalue>2.73238e-112</Hsp_evalue>
               <Hsp_num>1</Hsp_num>
               <Hsp_query-from>1</Hsp_query-from>
               <Hsp_query-to>173</Hsp_query-to>
               <Hsp_hit-from>194</Hsp_hit-from>
               <Hsp_hit-to>366</Hsp_hit-to>
               <Hsp_identity>173</Hsp_identity>
               <Hsp_positive>173</Hsp_positive>
               <Hsp_gaps>0</Hsp_gaps>
               <Hsp_align-len>173</Hsp_align-len>

       <Iteration_iter-num>2</Iteration_iter-num>
           <Hit_num>1</Hit_num>
               <Hsp>
               <Hsp_num>1</Hsp_num>
               <Hsp_evalue>2.41558e-119</Hsp_evalue>
               <Hsp_query-from>1</Hsp_query-from>
               <Hsp_query-to>173</Hsp_query-to>
               <Hsp_hit-from>194</Hsp_hit-from>
               <Hsp_hit-to>366</Hsp_hit-to>
               <Hsp_identity>173</Hsp_identity>
               <Hsp_positive>173</Hsp_positive>
               <Hsp_gaps>0</Hsp_gaps>
