## OCCURRENCE

### ARB_NT/ETC/PT Admin

## DESCRIPTION

### Allows you to start/kill and build/update 'PT_SERVER' databases.

### Select a 'PT_SERVER' and database from the menu displayed after pressing the button below the 'PT_SERVER' prompt.

### Start or kill the selected 'PT_SERVER' by pressing the corresponding buttons.

### Press the 'BUILD SERVER' button to export the current database to the selected 'PT_SERVER' database.

### In Genome Databases you may check the 'Gene server' toggle to build a PT-Server which is based on the sequences of the single genes (and intergene regions) of all organisms.

### Such a PT-Server allows to perform similarity searches and probe design/match for single genes (in opposite to whole genomes with a "normal" PT-Server).

### When designing probes with such a gene PT-Server you always have to validate these probes against a PT-Server build upon complete genome sequences, otherwise you will get incorrect results for all probes matching at beginning/end of a gene.

## NOTES

### Read PT_SERVER: What Why and How if you do not understand this helptext.

### The probe designing and matching tools ('ARB_PROBE') and the aligner of the editor ('ARB_EDIT4') rely on 'PT_SERVER' databases and servers.

### Update (re-build) the 'PT_SERVER' database when new sequence (species) entries or sequence modifications (base changes) have been introduced into the current database.
