Hi Stefanie,

If you click on the column name in the Gene Sorter, you will see the 
settings that were used in generating the column here:

Method
All known splice variants of all known human genes are put into a blast 
protein database using the formatdb program. This database is then 
searched with each known gene using version 2.2.5 of the NCBI blastall 
program with the following flags:

  -p blastp -e 0.01 -m 8 -b 1000


. . . does this explain the differences you are seeing?

If not, please feel free to write back to us at [email protected].
