How do I align my sequence with a single cDNA/mRNA/EST?
Use the –singleacc option. GrailEXP will look for the specified accession number in the specified list of databases. The accession number must be the same as the one used in the database, e.g. if the accession number in the database is AA393779.1, then just specifying AA393779 will NOT work. You can blame NCBI for this; version number should really be a separate field, as should organism.
