BLAST - Find similar sequences
STRAP allows to search public and private sequence databases to
identify sequences that are similar to a query sequences.
Depending on the type of sequences, there are four search methods:
- The query is an amino acid (aa) sequence and the database contains nucleotide (nt) sequences.
- ... nt ... nt. ...
- ... aa ... aa ...
- ... nt ... aa ...
By default the computation is performed on the EBI Blast server.
Strap as a front end provides advanced features compared to the web user interfaces of public services:
- Many jobs can be started simultaneously.
- The Blast result is saved in the cache. If the same query is used a
second time the result appears immediately.
-
Blast alert:
The sequence databases are permanently growing.
With the cache disabled STRAP conducts a new Blast
and compares the new result with the previous result stored in the cache.
It reports if there are new hits since last run and highlights all new hits.
- Several patterns can be highlighted.
Strap identifies patterns even if they are disrupted by a gap.
- Sequences from the hit-list can be loaded by mouse click.
