first concentrate on sequence + alignment

functional annotations

a given structure with unknown function -> BLAST at DDBJ / KEGG -> no homologs then -> struct-navi

• accession number -> fasta

• PDB ID <-> KEGG GENES ID get_linkdb_between_databases(string:from_db, string:to_db, int:offset, int:limit)

• PDB ID <-> DDDBJ ID

proposed workflow(s)

functional (or structural) annotation of a protein sequence.

Let's call this "funcanot" workflow.

let hits = BLAST_DAD(fasta) @DDBJ

if func_known(hits) then

send_to_KEGG( hits ) ;; annotation obtained from KEGG

else

let new_hits = BLAST_PDBj(fasta): @DDBJ

if exists(new_hits) then

foreach hit in new_hits do

let shits = struct_navi(hit) :@PDBj

if exists(shits) then

send_to_KEGG( shits );; annotation obtained from KEGG

input	amino acid sequence with unknown function
output	functionally annotated homologs

SOAP vs. REST

• SOAP isn't good at huge data (e.g., big XML file) <-> No problem with REST.
• REST requires more coding on the client side. User must handle output data (XML or flat text...) <-> SOAP can give you the object right away.
• REST cannot do complicated stuffs?
• No language supports the full SOAP spec.
• Only a few languages have SOAP libraries.

Prototyping funcanot

finally got to real work.... (14:00; 2008-02-12) Prototyping using Taverna.

• Taverna can be used with REST-based WS? -> YES!

Continuing funcanot 2008-02-13

• Taverna cannot really handle conditional branches: workflow just flows but not fork.
• added simple list format option to strnavi REST API.
• Have a Moby lecture?
