A nasty bug in the SRS link indexing

	Dear SRS developers and fellow SRS server managers,

While trying to implement a direct link between PIR and EMBL/GENBANK I
ran into trouble. After some searching I found that the cause was a bug
in the SRS software itself. It seems that when there is e.g. an Icarus
line :
$link:[@SWISSPROT_DB to:@?EMBL_DB token:'link|EMBL' toField:@DF_Accession]
not just tokens with code EMBL are put in the index, but all tokens.

To convince yourself of this, try the following :
search in SWISSPROT the entry with ID HA12_MOUSE
then make the link to EMBL
you will see that besides the two correct EMBL entries you also find
A02201 which is not related to the sequence SWISSPROT:HA12_MOUSE but
happens to have the same accession number as the corresponding PIR
entry.

SRS is great, but keeping it alive costs a lot of sweat and tears...

	Guy Bottu
